BAL Outflow Contribution to AGN Feedback: Frequency of S iv Outflows in the SDSS
Jay P. Dunn, Nahum Arav, Kentaro Aoki +4
We present a study of Broad Absorption Line (BAL) quasar outflows that show S IV ?1063 and S IV* ?1073 troughs. The fractional abundance of S IV and C IV peak at similar value of t…
Three-Dimensional Explosion Geometry of Stripped-Envelope Core-Collapse Supernovae. I. Spectropolarimetric Observations
Masaomi Tanaka, Koji S. Kawabata, Takashi Hattori +8
We study the multi-dimensional geometry of supernova (SN) explosions by means of spectropolarimetric observations of stripped-envelope SNe, i.e., SNe without a H-rich layer. We per…
GRB 100418A: a Long GRB without a Bright Supernova in a High-Metallicity Host Galaxy
Yuu Niino, Tetsuya Hashimoto, Kentaro Aoki +3
We present results of a search for a supernova (SN) component associated with GRB 100418A at the redshift of 0.624. The field of GRB 100418A was observed with FOCAS on Subaru 8.2m…
Identifying the Location in the Host Galaxy of the Short GRB 111117A with the Chandra Sub-arcsecond Position
T. Sakamoto, E. Troja, K. Aoki +31
We present our successful Chandra program designed to identify, with sub-arcsecond accuracy, the X-ray afterglow of the short GRB 111117A, which was discovered by Swift and Fermi.…
