Baryonic acoustic oscillations simulations for the Large Synoptic Survey Telescope (LSST)

The baryonic acoustic oscillations are features in the spatial distribution of the galaxies which, if observed at different epochs, probe the nature of the dark energy. In order to be able to measure the parameters of the dark energy equation of state to high precision, a huge sample of galaxies has to be used. The Large Synoptic Survey Telescope will survey the optical sky with 6 filters from 300nm and 1100nm, such that a catalog of galaxies with photometric redshifts will be available for dark energy studies. In this article, we will give a rough estimate of the impact of the photometric redshift uncertainties on the computation of the dark energy parameter through the reconstruction of the BAO scale from a simulated photometric catalog.Comment: 4 pages, 2 figures, 10th Rencontres de Blois proceedin

Still struggling to breathe: Another conversation on libraries and communities in crisis

In this lightning talk session, panelists will share brief statements regarding the roles of libraries in times of crises, including ideas such as navigating difficult conversations around anti-racism and other “controversial” topics; strategies for community resilience; the legal boundaries between free and hate speech; and how LIS education may play a role in preparing future LIS professionals for this type of crisis management. We also wish to interrogate the idea of the library as a place of neutrality. The remaining time will be spent facilitating an interactive discussion with the audience to strategize tangible action steps. Our initial work on this topic yielded several publications, which are listed below. Ironically, this work was not well received by the profession, but given the “supposed” racial reckoning that began after the death of George Floyd in the summer of 2020, we will reintroduce our work to the profession, which remains behind the curve on race relations, genuine and lasting inclusion, and anti racism. We continue our advocacy for ourselves, as BIPOC (black indigenous and people of color) faculty members, and for the future generations of the BIPOC information professionals we teach. Gibson, A.

Flipped Classrooms Panel

Flipped instruction is an instructional strategy where “students gain first exposure to new material outside of class, usually via reading or lecture videos, and then use class time to do the harder work of assimilating that knowledge, perhaps through problem-solving, discussion, or debates” (Cynthia J. Brame, Assistant Director, Center for Teaching, Vanderbilt University)

Separation of oceanic and continental crustal field signatures using Slepian functions

Models of the crustal magnetic field are typically represented using spherical harmonic coefficients. Rather than spherical harmonics, spherical Slepian functions can be employed to produce a locally and also globally orthogonal basis in which to optimally represent the available data in a region at a given degree. The region can have any arbitrary shape and size. The Slepian functions can be tailored to be either band- or space-limited, allowing a trade-off between spectral and spatial concentration in the region and leakage beyond. Another advantage is that only N Slepian coefficients are required to be solved for to optimally concentrate the energy of the Slepian functions into the region of interest (N = (L+1)2R/4π ; where N is the Shannon Number and R is the size of the region as a fraction of the full sphere) . We use N Slepian functions to optimally separate a crustal field model into its oceanic and continental regions in order to investigate the spectral content of each. Spherical harmonic coefficients are transformed into Slepian coefficients, separated into the appropriate regions and transformed back to spherical harmonic coefficients representing the space-limited extent of the oceans and continents. The spectral power of each region is examined over degrees L = 16-72. We show that both regions display different power levels at discrete bandwidths. For example, the oceanic signal dominates at degrees 16-30, while the continental signal is stronger at degrees 45-65. We compare different crustal models to illustrate that the derived signals are robust

Taxonomic revision of the genus Stenocyphus Marshall (Coleoptera, Curculionidae) from Brazil

Stenocyphus Marshall, 1922 (Entiminae, Naupactini) includes three species: the type species S. bituberosus (Gyllenhal, 1833), S. tuberculatus (Hustache, 1938), comb. n. herein transferred from Neoericydeus Hustache, 1938, and S. sextuberosus sp. n. The genus is endemic to the Atlantic forests of the states of Espirito Santo, Rio de Janeiro and São Paulo, Brazil and is mainly characterized by the presence of humped elytra bearing large conical tubercles on the intervals 5, or 3 and 5, or 3, 5 and 7. It shares some external morphological characters with Hadropus Schoenherr, 1826 and the Brazilian species of Cyrtomon Schoenherr 1823, but its phylogenetic position is uncertain. Herein we provide a diagnostic key to separate Stenocyphus from those genera, generic and species redescriptions or descriptions, a key to species, habitus photographs, line drawings of genitalia, and a discussion of the patterns of elytral tubercles in unrelated genera of Neotropical broad-nosed weevils.Fil: del Rio, Maria Guadalupe.

Simulations of Cosmic Chemical Enrichment with Hypernova

We simulate cosmic chemical enrichment with a hydrodynamical model including supernova and hypernova feedback. We find that the majority of stars in present-day massive galaxies formed in much smaller galaxies at high redshifts, despite their late assembly times. The hypernova feedback drives galactic outflows efficiently in low mass galaxies, and these winds eject heavy elements into the intergalactic medium. The ejected baryon fraction is larger for less massive galaxies, correlates well with stellar metallicity. The observed mass-metallicity relation is well reproduced as a result of the mass-dependent galactic winds. We also predict the cosmic supernova and gamma-ray burst rate histories.Comment: Proceedings of the CRAL-Conference Series I "Chemodynamics: from first stars to local galaxies
