Analytic approximations for transit light curve observables and uncertainties
Joshua A. Carter, Jennifer C. Yee, Jason Eastman +2
The light curve of an exoplanetary transit can be used to estimate the planetary radius and other parameters of interest. Because accurate parameter estimation is a non-analytic an…
Analytic Approximations for Transit Light Curve Observables, Uncertainties, and Covariances
Joshua A. Carter, Jennifer C. Yee, Jason Eastman +2
The light curve of an exoplanetary transit can be used to estimate the planetary radius and other parameters of interest. Because accurate parameter estimation is a non-analytic an…
A Study of the Type Ia/IIn Supernova 2005gj from X-ray to the Infrared: Paper I
J. L. Prieto, P. M. Garnavich, M. M. Phillips +53
We present extensive ugrizYHJK photometry and optical spectroscopy of SN 2005gj obtained by the SDSS-II and CSP Supernova Projects, which give excellent coverage during the first 1…
First Measurement of a Rapid Increase in the AGN Fraction in High-Redshift Clusters of Galaxies
Jason Eastman, Paul Martini, Gregory Sivakoff +3
We present the first measurement of the AGN fraction in high-redshift clusters of galaxies (z~0.6) with spectroscopy of one cluster and archival data for three additional clusters.…
Exploring Broadband GRB Behavior During gamma-ray Emission
S. A. Yost, H. F. Swan, E. S. Rykoff +44
The robotic ROTSE-III telescope network detected prompt optical emission contemporaneous with the gamma-ray emission of Swift events GRB051109A and GRB051111. Both datasets have co…
The Peculiar SN 2005hk: Do Some Type Ia Supernovae Explode as Deflagrations?
M. M. Phillips, W. Li, J. A. Frieman +41
We present extensive u'g'r'i'BVRIYJHKs photometry and optical spectroscopy of SN 2005hk. These data reveal that SN 2005hk was nearly identical in its observed properties to SN 2002…
