Variable Sodium Absorption in a Low-Extinction Type Ia Supernova
Joshua D. Simon, Avishay Gal-Yam, Orly Gnat +18
Recent observations have revealed that some Type Ia supernovae exhibit narrow, time-variable Na I D absorption features. The origin of the absorbing material is controversial, but…
On the Connection Between Metal Absorbers and Quasar Nebulae
Doron Chelouche, Brice Ménard, David V. Bowen +1
We establish a simple model for the distribution of cold gas around L* galaxies using a large set of observational constraints on the properties of strong MgII absorber systems. Ou…
Time-Dependent Ionization in Radiatively Cooling Gas
Orly Gnat, Amiel Sternberg
We present new computations of the equilibrium and non-equilibrium cooling efficiencies and ionization states for low-density radiatively cooling gas containing cosmic abundances o…
Photoionized Gas in Dark-Matter Minihalos in the Galactic Halo and Local Group
Orly Gnat, Amiel Sternberg
(Abridged) We present computations of the metals photoionization structures of pressure supported gas clouds in gravitationally dominant DM minihalos in the extended Galactic halo…
