Ionization Modeling Astrophysical Gaseous Structures. I. The Optically Thin Regime
Christopher W. Churchill, Elizabeth Klimek, Amber Medina +1
We present a code for modelling the ionization conditions of optically thin astrophysical gas structures. Given the gas hydrogen density, equilibrium temperature, elemental abundan…
New Perspective on Galaxy Outflows From the First Detection of Both Intrinsic and Traverse Metal-Line Absorption
Glenn G. Kacprzak, Crystal L. Martin, Nicolas Bouché +6
We present the first observation of a galaxy (z=0.2) that exhibits metal-line absorption back-illuminated by the galaxy ("down-the-barrel") and transversely by a background quasar…
Radiative feedback and the low efficiency of galaxy formation in low-mass haloes at high redshift
Daniel Ceverino, Anatoly Klypin, Elizabeth Klimek +4
Any successful model of galaxy formation needs to explain the low rate of star formation in the small progenitors of today's galaxies. This inefficiency is necessary for reproducin…
The Redshift Distribution of Intervening Weak MgII Quasar Absorbers and a Curious Dependence on Quasar Luminosity
Jessica L. Evans, Christopher W. Churchill, Michael T. Murphy +2
We have identified 469 MgII doublet systems having W_r >= 0.02 Å in 252 Keck/HIRES and UVES/VLT quasar spectra over the redshift range 0.1 < z < 2.6. Using the largest sample yet o…
Reverberation Mapping Measurements of Black Hole Masses in Six Local Seyfert Galaxies
K. D. Denney, B. M. Peterson, R. W. Pogge +40
We present the final results from a high sampling rate, multi-month, spectrophotometric reverberation mapping campaign undertaken to obtain either new or improved Hbeta reverberati…
Diverse Broad Line Region Kinematic Signatures From Reverberation Mapping
K. D. Denney, B. M. Peterson, R. W. Pogge +40
A detailed analysis of the data from a high sampling rate, multi-month reverberation mapping campaign, undertaken primarily at MDM Observatory with supporting observations from tel…
