The Reddening Towards Cassiopeia A's Supernova: Constraining the 56Ni Yield (2009)
Eriksen, Kristoffer A., Arnett, David, McCarthy, Donald W., Young, Patrick
We present new reddening measurements towards the young supernova remnant Cassiopeia A, using two techniques not previously applied to this object. Our observations of the near-infrared [Fe II] 1.257...

The Lyman-alpha forest has opened a new redshift regime for cosmological investigation. At z > 2 it provides a unique probe of cosmic geometry and an independent constraint on dark energy that is not...

The isotropy of the Lyman-alpha forest in real-space uniquely provides a measurement of cosmic geometry at z > 2. The angular diameter distance for which the correlation function along the line of...
Constraints on the Progenitor of Cassiopeia A (2005)
Young, Patrick A., Fryer, Chris L., Hungerford, Aimee, Arnett, David, Rockefeller, Gabriel, Timmes, F. X., ...
We compare a suite of 3D explosion calculations and stellar models incorporating advanced physics with observational constraints on the progenitor of Cassiopeia A. We consider binary and single stars...

We present observations of the young, Oxygen-rich supernova remnant 1E0102.2-7219 taken by the Chandra X-ray Observatory during Chandra's Orbital Activation and Checkout phase. The boundary of the...
