Time evolution of the line emission from the inner circumstellar ring of SN 1987A and its hot spots
Per Groeningsson, Claes Fransson, Bruno Leibundgut +4
We present seven epochs between October 1999 and November 2007 of high resolution VLT/UVES echelle spectra of the ejecta-ring collision of SN 1987A. The fluxes of most of the narro…
From Shock Breakout to Peak and Beyond: Extensive Panchromatic Observations of the Type Ib Supernova 2008D associated with Swift X-ray Transient 080109
Maryam Modjaz, W. Li, N. Butler +38
We present extensive early photometric (ultraviolet through near-infrared) and spectroscopic (optical and near-infrared) data on supernova (SN) 2008D as well as X-ray data analysis…
XMM-Newton slew survey discovery of the nova XMMSL1 J070542.7-381442 (V598 Pup)
A. M. Read, R. D. Saxton, M. A. P. Torres +6
In an attempt to catch new X-ray transients while they are still bright, the data taken by XMM-Newton as it slews between targets is being processed and cross-correlated with other…
Type Ia Supernovae are Good Standard Candles in the Near Infrared: Evidence from PAIRITEL
W. Michael Wood-Vasey, Andrew S. Friedman, Joshua S. Bloom +11
We have obtained 1087 NIR (JHKs) measurements of 21 SNe Ia using PAIRITEL, nearly doubling the number of well-sampled NIR SN Ia light curves. These data strengthen the evidence tha…
Measured Metallicities at the Sites of Nearby Broad-Lined Type Ic Supernovae and Implications for the SN-GRB Connection
M. Modjaz, L. Kewley, R. P. Kirshner +6
We compare the chemical abundances at the sites of 12 nearby (z <0.14) Type Ic supernovae (SN Ic) that showed broad lines, but had no observed Gamma-Ray Burst (GRB), with the chemi…
