A First Transients Survey with JWST: the FLARE project
Lifan Wang, D. Baade, E. Baron +43
JWST was conceived and built to answer one of the most fundamental questions that humans can address empirically: "How did the Universe make its first stars?". Our First Lights At…
Type II supernova spectral diversity II: Spectroscopic and photometric correlations
Claudia P. Gutiérrez, Joseph P. Anderson, Mario Hamuy +7
We present an analysis of observed trends and correlations between a large range of spectral and photometric parameters of more than 100 type II supernovae (SNe~II), during the pho…
Type II supernova spectral diversity I: Observations, sample characterization and spectral line evolution
Claudia P. Gutiérrez, Joseph P. Anderson, Mario Hamuy +23
We present 888 visual-wavelength spectra of 122 nearby type II supernovae (SNe II) obtained between 1986 and 2009, and ranging between 3 and 363 days post explosion. In this first…
The Carnegie Supernova Project I: Third Photometry Data Release of Low-Redshift Type Ia Supernovae and Other White Dwarf Explosions
Kevin Krisciunas, Carlos Contreras, Christopher R. Burns +27
We present final natural system optical (ugriBV) and near-infrared (YJH) photometry of 134 supernovae (SNe) with probable white dwarf progenitors that were observed in 2004-2009 as…
Light and color curve properties of type Ia supernovae: Theory vs. Observations
P. Hoeflich, E. Y. Hsiao, C. Ashall +10
We study optical light curve(LC) relations of type Ia supernovae(SNe~Ia) for their use in cosmology using high-quality photometry published by the Carnegie-Supernovae-Project (CSP-…
SPIRITS: Uncovering Unusual Infrared Transients With Spitzer
Mansi M. Kasliwal, John Bally, Frank Masci +44
We present an ongoing, systematic search for extragalactic infrared transients, dubbed SPIRITS --- SPitzer InfraRed Intensive Transients Survey. In the first year, using Spitzer/IR…
