Assisted stellar suicide in V617 Sgr

J. E. Steiner, A. S. Oliveira, D. Cieslinski +1

V617 Sgr is a V Sagittae star - a group of binaries thought to be the galactic counterparts of the Compact Binary Supersoft X-ray Sources - CBSS. To check this hypothesis, we measu…

The luminosity function of the fossil group RX J1552.2+2013

Claudia L. Mendes de Oliveira, Eduardo S. Cypriano, Laerte Sodre

We determine the first fossil group luminosity function based on spectroscopy of the member galaxies. The fossil group RX J1552.2+2013 has 36 confirmed members, it is at a mean red…

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…

Gemini and Chandra observations of Abell 586, a relaxed strong-lensing cluster

E. S. Cypriano, G. B. Lima Neto, L. Sodré +2

We analyze the mass content of the massive strong-lensing cluster Abell 586 ( $z = 0.17$ ). We use optical data (imaging and spectroscopy) obtained with the Gemini Multi-Object Spect…
