Dust and the type II-plateau supernova 2004et (2009)

Kotak, Rubina, Meikle, Peter, Farrah, Duncan, Gerardy, Christopher, Foley, Ryan, Van Dyk, Schuyler, ...

We present mid-infrared (MIR) observations of the Type II-plateau supernova (SN) 2004et, obtained with the {\it Spitzer Space Telescope} between days 64 and 1406 past explosion. Late-time optical...

Multicolor Infrared Observations of SN 2006aj, the Supernova Associated with XRF 060218 - Paper I (2006)

Kocevski, Daniel, Modjaz, Maryam, Bloom, Joshua S., Foley, Ryan, Starr, Daniel, Blake, Cullen H., ...

We report simultaneous multicolor near-infrared (NIR) observations of the supernova associated with x-ray Flash 060218 during the first 16 days after the high energy event. We find that the light...

New Hubble Space Telescope Discoveries of Type Ia Supernovae at z > 1: Narrowing Constraints on the Early Behavior of Dark Energy (2006)

Riess, Adam G., Strolger, Louis-Gregory, Casertano, Stefano, Ferguson, Henry C., Mobasher, Bahram, Gold, Ben, ...

We have discovered 21 new Type Ia supernovae (SNe Ia) with the Hubble Space Telescope (HST) and have used them to trace the history of cosmic expansion over the last 10 billion years. These objects,...

Spitzer measurements of atomic and molecular abundances in the Type IIP SN 2005af (2006)

Kotak, Rubina, Meikle, Peter, Pozzo, Monica, Van Dyk, Schuyler D., Farrah, Duncan, Fesen, Robert, ...

We present results based on Spitzer Space Telescope mid-infrared (3.6-30 micron) observations of the nearby IIP supernova 2005af. We report the first ever detection of the SiO molecule in a Type IIP...

The Type IIn Supernova 2002kg: The Outburst of a Luminous Blue Variable Star in NGC 2403 (2006)

Van Dyk, Schuyler D., Li, Weidong, Filippenko, Alexei V., Humphreys, Roberta M., Chornock, Ryan, Foley, Ryan, ...

We show that Supernova (SN) 2002kg in NGC 2403, initially classified as Type II-narrow (IIn), has photometric and spectroscopic properties unlike those of normal SNe. Its behavior, instead, is more...

Supernova Cosmology and the ESSENCE project (2005)

Sollerman, Jesper, Aguilera, Claudio, Becker, Andy, Blondin, Stephane, Challis, Pete, Clocchiatti, Alejandro, ...

The proper usage of Type Ia supernovae (SNe Ia) as distance indicators has revolutionized cosmology, and added a new dominant component to the energy density of the Universe, dark energy. Following...
