From Hegel to Paz: Re-reading Orientalism in Latin American Writing

Over the past few decades, the presence of Asia in the history of Latin American literature has received considerable scholarly attention. An increasing number of studies on Asia in relation to Latin American politics and economy has been accompanied by a growing interest in cultural relations between these geographically distant regions. While the trans-Atlantic ties between Europe and Latin America have been scrutinized by critics for many years, the analysis of a trans-Pacific connection is still considered to be a relatively new subject. In general, previous research can be divided into two main branches. On the one hand are the scholars who have explored the ways in which the “exotic” Orient has attracted generations of Latin American writers since the nineteenth century. On the other hand are the studies that focus on more contemporary issues, such as the influence of Asian immigrants in different Latin American countries, most notably Cuba, Peru, Mexico, Argentina and Brazil. These studies look at both the contributions of the Asian Diaspora in the making of a modern Latin America and the ways in which this cultural encounter manifests itself in diverse forms, including literature, art, music, cuisine and fashion

Between the Empires: Martí, Rizal and the Limits of Global Resistance

This dissertation aims to compare and contrast an aspect of the fin-de-siècle literature and history of anti-imperialism in Cuba and the Philippines. I focus my study on what may be the most prominent authors of the two contexts: José Martí (1853-1895) and José Rizal (1861-1896). Although scholars such as Benedict Anderson and Leopoldo Zea have already noted the obvious relations between Martí and Rizal, their anti-imperial texts have not been systematically compared. Caught between the two empires (Spain and the United States), their projects were equally overwhelming: while studying the history of the failed independence movement in their respective colonies, they attempted to transform the dilemmas of imperial culture into the building blocks for national liberation. Based on this historico-political premise, my study attempts to explore how Martí and Rizal employ different literary forms to articulate their discourse of protest and to what extent their political writings create the conditions of possibility for a transnational, inter-colonial form of resistance against imperial domination. One of the central contentions of this dissertation is that the two writers’ anti-imperial texts construct the conceptual framework for the idea of what I call “global resistance.” By this, I mean to indicate the ways in which Cubans and Filipinos shared certain anti-colonial ideas and struggles against common opponents in the nineteenth century. Through literary analysis and historical study, I intend to examine both the possibilities and the limits of global resistance. The project involves diverse cultural points of reference, ranging from the Caribbean to Asia and seeking to participate in the ongoing debate within the field of Trans-Pacific Studies

Phenomenology of NMSSM in TeV scale mirage mediation

We study the next-to-minimal supersymmetric standard model (NMSSM) with the TeV scale mirage mediation, which is known as a solution for the little hierarchy problem in supersymmetry. Our previous study showed that 125 GeV Higgs boson is realized with O(10) % fine-tuning for 1.5 TeV gluino (1 TeV stop) mass. The $\mu$ term could be as large as 500 GeV without sacrificing the fine-tuning thanks to a cancellation mechanism. The singlet-doublet mixing is suppressed by $\tan\beta$. In this paper, we further extend this analysis. We argue that approximate scale symmetries play a role behind the suppression of the singlet-doublet mixing. They reduce the mixing matrix to a simple form that is useful to understand the results of the numerical analysis. We perform a comprehensive analysis of the fine-tuning including the singlet sector by introducing a simple formula for the fine-tuning measure. This shows that the singlet mass of the least fine-tuning is favored by the LEP anomaly for moderate $\tan\beta$. We also discuss prospects for the precision measurements of the Higgs couplings at LHC and ILC and direct/indirect dark matter searches in the model.Comment: 47 pages, 46 figures, version accepted by JHE

Measures of non-Gaussianity in axion-string-induced CMB birefringence

The presence of axion strings in the Universe after recombination can leave an imprint on the polarization pattern of the cosmic microwave background radiation through the phenomenon of axion-string-induced birefringence via the hyperlight axion-like particle's coupling to electromagnetism. Across the sky, the polarization rotation angle is expected to display a patchwork of uniform regions with sharp boundaries that arise as the `shadow' of axion string loops. The statistics of such a birefringence sky map are therefore necessarily non-Gaussian. In this article we quantify the non-Gaussianity in axion-string-induced birefringence using two techniques, kurtosis and bispectrum, which correspond to $4$- and $3$-point correlation functions. If anisotropic birefringence were detected in the future, a measurement of its non-Gaussian properties would facilitate a discrimination across different new physics sources generally, and in the context of axion strings specifically, it would help to break degeneracies between the axion-photon coupling and properties of the string network.Comment: 12 pages, plus appendix, 6 figure

Symmetries of CMB Temperature Correlation at Large Angular Separations

A new analysis is presented of the angular correlation function $C(\Theta)$ of cosmic microwave background (CMB) temperature at large angular separation, based on published maps derived from {\sl WMAP} and {\sl Planck} satellite data, using different models of astrophysical foregrounds. It is found that using a common analysis, the results from the two satellites are very similar. In particular, it is found that previously published differences between measured values of $C(\Theta)$ near $\Theta=90^\circ$ arise mainly from different choices of masks in regions of largest Galactic emissions, and that demonstrated measurement biases are reduced by eliminating masks altogether. Maps from both satellites are shown to agree with $C(90^\circ)=0$ to within estimated statistical and systematic errors, consistent with an exact symmetry predicted in a new holographic quantum model of inflation.Comment: resubmitted to ApJ Letters, with revisions in response to referee comment

Searching for axion-like particles through CMB birefringence from string-wall networks

Axion-like particles (ALPs) can form a network of cosmic strings and domain walls that survives after recombination and leads to anisotropic birefringence of the cosmic microwave background (CMB). In addition to studying cosmic strings, we clarify and emphasize how the formation of ALP-field domain walls impacts the cosmic birefringence signal; these observations provide a unique way of probing ALPs with masses in the range $3H_0 \lesssim m_a \lesssim 3H_{\rm cmb}$. Using measurements of CMB birefringence from several telescopes, we find no evidence for axion-defect-induced anisotropic birefringence of the CMB. We extract constraints on the model parameters that include the ALP mass $m_a$, ALP-photon coupling $\mathcal{A} \propto g_{a\gamma\gamma} f_a$, the domain wall number $N_{\rm dw}$, and parameters characterizing the abundance and size of defects in the string-wall network. Considering also recent evidence for isotropic CMB birefringence, we find it difficult to accommodate this with the non-detection of anisotropic birefringence under the assumption that the signal is generated by an ALP defect network.Comment: 20 pages + 3 appendices, 14 figures, 3 table

FLASH: Faint Lenses from Associated Selection with Herschel

We report the ALMA Band 7 observations of 86 Herschel sources that likely contain gravitationally-lensed galaxies. These sources are selected with relatively faint 500 $\mu$m flux densities between 15 to 85 mJy in an effort to characterize the effect of lensing across the entire million-source Herschel catalogue. These lensed candidates were identified by their close proximity to bright galaxies in the near-infrared VISTA Kilo-Degree Infrared Galaxy Survey (VIKING) survey. Our high-resolution observations (0.15 arcsec) confirm 47 per cent of the initial candidates as gravitational lenses, while lensing cannot be excluded across the remaining sample. We find average lensing masses (log M/M$_{\odot}$ = 12.9 $\pm$ 0.5) in line with previous experiments, although direct observations might struggle to identify the most massive foreground lenses across the remaining 53 per cent of the sample, particularly for lenses with larger Einstein radii. Our observations confirm previous indications that more lenses exist at low flux densities than expected from strong galaxy-galaxy lensing models alone, where the excess is likely due to additional contributions of cluster lenses and weak lensing. If we apply our method across the total 660 sqr. deg. H-ATLAS field, it would allow us to robustly identify 3000 gravitational lenses across the 660 square degree Herschel ATLAS fields.Comment: Accepted for publication in MNRAS.

Accurate dust temperature determination in a z = 7.13 galaxy

We report ALMA Band 9 continuum observations of the normal, dusty star-forming galaxy A1689-zD1 at z = 7.13, resulting in a ∼4.6 σ detection at 702 GHz. For the first time, these observations probe the far-infrared spectrum shortward of the emission peak of a galaxy in the Epoch of Reionization (EoR). Together with ancillary data from earlier works, we derive the dust temperature, Td, and mass, Md, of A1689-zD1 using both traditional modified blackbody spectral energy density fitting, and a new method that relies only on the [C ii] 158 μm line and underlying continuum data. The two methods give Td = (42+13-7, 40+13-) K, and Md} = (1.7+1.3-0.7, 2.0+1.8-1.0), 7, 107, M⊙. Band 9 observations improve the accuracy of the dust temperature (mass) estimate by ∼50 per cent (6 times). The derived temperatures confirm the reported increasing Td-redshift trend between z = 0 and 8; the dust mass is consistent with a supernova origin. Although A1689-zD1 is a normal UV-selected galaxy, our results, implying that ∼85 per cent of its star-formation rate is obscured, underline the non-negligible effects of dust in EoR galaxies
