NuSTAR hard X-ray data and Gemini 3D spectra reveal powerful AGN and outflow histories in two low-redshift Lyman- blobs
We have shown that Lyman- blobs (LABs) may still exist even at
, about 7 billion years later than most other LABs known (Schirmer et
al. 2016). Their luminous Ly and [OIII] emitters at offer
new insights into the ionization mechanism. This paper focuses on the two X-ray
brightest LABs at , SDSS J01130106 (J0113) and SDSS J11550147
(J1155), comparable in size and luminosity to `B1', one of the best-studied
LABs at 2. Our NuSTAR hard X-ray (3--30 keV) observations reveal
powerful active galactic nuclei (AGN) with -- erg cm s. J0113 also faded by a
factor of between 2014 and 2016, emphasizing that variable AGN may
cause apparent ionization deficits in LABs. Joint spectral analyses including
Chandra data constrain column densities of cm (J0113) and cm (J1155). J0113 is likely buried in
a torus with a narrow ionization cone, but ionizing radiation is also leaking
in other directions as revealed by our Gemini/GMOS 3D spectroscopy. The latter
shows a bipolar outflow over kpc, with a peculiar velocity profile that is
best explained by AGN flickering. X-ray analysis of J1155 reveals a weakly
absorbed AGN that may ionize over a wide solid angle, consistent with our 3D
spectra. Extinction corrected [OIII] log-luminosities are high, . The
velocity dispersions are low, -- km s, even at the AGN
positions. We argue that this is a combination of high extinction hiding the
turbulent gas, and previous outflows that have cleared the escape paths for
their successors.Comment: 15 pages, 17 Figures, accepted for publication in Ap
[S IV] in the NGC 5253 Supernebula: Ionized Gas Kinematics at High Resolution
The nearby dwarf starburst galaxy NGC 5253 hosts a deeply embedded
radio-infrared supernebula excited by thousands of O stars. We have observed
this source in the 10.5{\mu}m line of S+3 at 3.8 kms-1 spectral and 1.4"
spatial resolution, using the high resolution spectrometer TEXES on the IRTF.
The line profile cannot be fit well by a single Gaussian. The best simple fit
describes the gas with two Gaussians, one near the galactic velocity with FWHM
33.6 km s-1 and another of similiar strength and FWHM 94 km s-1 centered \sim20
km s-1 to the blue. This suggests a model for the supernebula in which gas
flows towards us out of the molecular cloud, as in a "blister" or "champagne
flow" or in the HII regions modelled by Zhu (2006).Comment: Accepted for publication in the Astrophysical Journal 4 June 201
Numerical solution of the Navier-Stokes equations for arbitrary two-dimensional multi-element airfoils
The development of a numerical simulation of time dependent, turbulent, compressible flow about two dimensional multi-element airfoils of arbitrary shape is described. The basis of this simulation is a technique of automatic numerical generation of coordinate systems fitted to the multiple bodies regardless of their number or shape. Procedures developed whereby the coordinate lines are automatically concentrated in the boundary layer at any Reynolds number are discussed. The compressible turbulent solution involves an algebraic eddy viscosity turbulence model. The laminar version was run for transonic flow at free stream Mach numbers up to 0.9
Chromosome Complements in Desmanthus (Leguminosae)
Desmanthus, a genus of the subfamily Mimosoideae of the Leguminosae, is represented in the United States by ten species, one of which has two varieties. Nine species are found in Texas (Turner, 1950b). The genus has its greatest concentration in Mexico where sixteen species occur (Turner, 1950a). In the present paper chromosome studies on Desmanthus acuminatus, D. brevipes, D. leptolobus, D. velutinus and D. virgatus var. depressus are reported. These five species occur in Texas
The History and Practice of College Health
This volume is the first definitive reference and textbook in the one-hundred-fifty year history of college health. Written for professionals and for those working in student services and higher education administration, it covers the history of college health, administrative matters including financing and accreditation, and clinical issues such as women’s health, HIV/AIDS, and mental health. The book also focuses on prevention, including immunization and tuberculin testing. The contributors are well respected in the field and are actively working in the specific areas on which they write.
