Discovery and identification of the very high redshift afterglow of GRB 050904
J. Haislip, M. Nysewander, D. Reichart +39
In 2000, Lamb and Reichart predicted that gamma-ray bursts (GRBs) and their afterglows occur in sufficient numbers and at sufficient brightnesses at very high redshifts (z > 5) to…
GRB070610 : A Curious Galactic Transient
M. M. Kasliwal, S. B. Cenko, S. R. Kulkarni +23
GRB 070610 is a typical high-energy event with a duration of 5s.Yet within the burst localization we detect a highly unusual X-ray and optical transient, SwiftJ195509.6+261406. We…
Slow blue nuclear hypervariables in PanSTARRS-1
A. Lawrence, A. G. Bruce, C. MacLeod +23
We discuss 76 large amplitude transients (Delta-m>1.5) occurring in the nuclei of galaxies, nearly all with no previously known Active Galactic Nucleus (AGN). They have been discov…
The Structure and Stellar Content of the Outer Disks of Galaxies: A New View from the Pan-STARRS1 Medium Deep Survey
Z. Zheng, D. Thilker, T. Heckman +11
We present the results of an analysis of Pan-STARRS1 Medium Deep Survey multi-band (g,r,i,z,y) images of a sample of 698 low-redshift disk galaxies that span broad ranges in stella…
The GRB Host Galaxies and Redshifts
S. G. Djorgovski, S. R. Kulkarni, J. S. Bloom +12
Observations of GRB host galaxies and their environments in general can provide valuable clues about the nature of progenitors. Bursts are associated with faint, <R> ~ 25 mag, gala…
PROMPT: Panchromatic Robotic Optical Monitoring and Polarimetry Telescopes
D. Reichart, M. Nysewander, J. Moran +11
Funded by $1.2M in grants and donations, we are now building PROMPT at CTIO. When completed in late 2005, PROMPT will consist of six 0.41-meter diameter Ritchey-Chretien telescopes…
