A Model-Insensitive Baryon Acoustic Oscillation Feature in the 21 cm Signal from Reionization
Christopher Cain, Anson D'Aloisio, Vid Iršič +2
We examine the impact of baryon-dark matter relative velocities on intergalactic small-scale structure and the 21 cm signal during reionization. Streaming velocities reduced clumpi…
Hydrodynamic Response of the Intergalactic Medium to Reionization
Anson D'Aloisio, Matthew McQuinn, Hy Trac +2
The intergalactic medium is expected to clump on scales down to M before the onset of reionization. The impact of these small-scale structures on reionization…
Investigating the Unusual Spectroscopic Time-Evolution in SN 2012fr
C. Cain, E. Baron, M. M. Phillips +9
The type Ia supernova (SN) 2012fr displayed an unusual combination of its Si II λλ5972, 6355 features. This includes the ratio of their pseudo equivalent widths, placing it at the…
SN 2012fr: Ultraviolet, Optical, and Near-Infrared Light Curves of a Type Ia Supernova Observed Within a Day of Explosion
Carlos Contreras, M. M. Phillips, Christopher R. Burns +32
We present detailed ultraviolet, optical and near-infrared light curves of the Type Ia supernova (SN) 2012fr, which exploded in the Fornax cluster member NGC 1365. These precise hi…
