PTF11kx: A Type-Ia Supernova with a Symbiotic Nova Progenitor
B. Dilday, D. A. Howell, S. B. Cenko +32
There is a consensus that Type-Ia supernovae (SNe Ia) arise from the thermonuclear explosion of white dwarf stars that accrete matter from a binary companion. However, direct obser…
Broad-Line Reverberation in the Kepler-Field Seyfert Galaxy Zw 229-015
A. J. Barth, M. L. Nguyen, M. A. Malkan +45
The Seyfert 1 galaxy Zw 229-015 is among the brightest active galaxies being monitored by the Kepler mission. In order to determine the black hole mass in Zw 229-015 from H-beta re…
A Golden Standard Type Ia Supernova SN 2005cf: Observations from the Ultraviolet to the Near-Infrared Wavebands
Xiaofeng Wang, Weidong Li, Alexei V. Filippenko +31
We present extensive photometry at ultraviolet (UV), optical, and near-infrared (NIR) wavelengths, as well as dense sampling of optical spectra, for the normal type Ia supernova (S…
The transverse proximity effect in the z ~ 2 Lyman-alpha forest suggests QSO episodic lifetimes of ~1 Myr
David Kirkman, David Tytler
We look for signs of the H~I transverse proximity effect in the spectra of 130 QSO pairs, most with transverse separations in the plane of the sky of 0.1 -- 3 Mpc at z ~ 2.2. We ex…
The Lyman-alpha forest at redshifts 0.1 -- 1.6: good agreement between a large hydrodynamic simulation and HST spectra
Pascal Paschos, Tridivesh Jena, David Tytler +2
We give a comprehensive statistical description of the Lyman-alpha absorption from the intergalactic medium in a hydrodynamic simulation at redshifts 0.1-1.6, the range of redshift…
The Effect of Large-Scale Power on Simulated Spectra of the Lya forest
David Tytler, Pascal Paschos, David Kirkman +2
We study the effects of box size on ENZO simulations of the intergalactic medium (IGM) at z = 2. We follow statistics of the cold dark matter (CDM) and the Lya absorption. We find…
