PS1-13cbe: The Rapid "Turn on" of a Seyfert 1

Reza Katebi, Ryan Chornock, Edo Berger +11

We present a nuclear transient event, PS1-13cbe, that was first discovered in the Pan-STARRS1 survey in 2013. The outburst occurred in the nucleus of the galaxy SDSS J222153.87+003…

Galaxy inclination and the IRX-beta relation: Effects on UV star-formation rate measurements at intermediate to high redshifts

Weichen Wang, Susan A. Kassin, Camilla Pacifici +11

At intermediate and high redshifts, measurements of galaxy star-formation rates are usually based on rest-frame ultraviolet (UV) data. A correction for dust attenuation, A_UV, is n…
