CfA3: 185 Type Ia Supernova Light Curves from the CfA

Malcolm Hicken, Peter Challis, Saurabh Jha +5

We present multi-band photometry of 185 type-Ia supernovae (SN Ia), with over 11500 observations. These were acquired between 2001 and 2008 at the F. L. Whipple Observatory of the…

Dissecting the Red Sequence--I. Star Formation Histories of Quiescent Galaxies: The Color-Magnitude vs. the Color-Sigma Relation

Genevieve J. Graves, S. M. Faber, Ricardo P. Schiavon

We use a sample of ~16,000 non-emission line galaxies from the SDSS to investigate the physical parameters underlying the well-known color-magnitude and color-sigma relations. Gala…

Optical Spectroscopy of Type Ia Supernovae

T. Matheson, R. P. Kirshner, P. Challis +19

We present 432 low-dispersion optical spectra of 32 Type Ia supernovae (SNe Ia) that also have well-calibrated light curves. The coverage ranges from 6 epochs to 36 epochs of spect…

Measuring Ages and Elemental Abundances from Unresolved Stellar Populations: Fe, Mg, C, N, and Ca

Genevieve J. Graves, Ricardo P. Schiavon

We present a method for determining mean light-weighted ages and abundances of Fe, Mg, C, N, and Ca, from medium resolution spectroscopy of unresolved stellar populations. The meth…

Ages and Abundances of Red Sequence Galaxies as a Function of LINER Emission Line Strength

Genevieve J. Graves, Sandra M. Faber, Ricardo P. Schiavon +1

Although the spectrum of a prototypical early-type galaxy is assumed to lack emission lines, a substantial fraction (likely as high as 30%) of nearby red sequence galaxy spectra co…

UBVRI Light Curves of 44 Type Ia Supernovae

Saurabh Jha, Robert P. Kirshner, Peter Challis +2

We present UBVRI photometry of 44 type-Ia supernovae (SN Ia) observed from 1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence Whipple Observatory of the…
