We estimate the dust extinction laws in two intermediate-redshift galaxies. The dust in the lens galaxy of LBQS 1009-0252, which has an estimated lens redshift...
The extraordinarily bright optical afterglow of GRB 991208 and its host galaxy
Broad-band optical observations of the extraordinarily bright optical afterglow of the intense gamma-ray burst GRB 991208 started ~2.1 days after the event and...
The Extreme CNO-enhanced Composition of the Primitive Iron-poor Dwarf Star J0815+4729
We present an analysis of high-resolution Keck/HIRES spectroscopic observations of J0815+4729, an extremely carbon-enhanced, iron-poor dwarf star. These high...
The Extreme CNO-enhanced Composition of the Primitive Iron-poor Dwarf Star J0815+4729
We present an analysis of high-resolution Keck/HIRES spectroscopic observations of J0815+4729, an extremely carbon-enhanced, iron-poor dwarf star. These high...
The extremely low-metallicity tail of the Sculptor dwarf spheroidal galaxy
We present abundances for seven stars in the (extremely) low-metallicity tail of the Sculptor dwarf spheroidal galaxy, from spectra taken with X-shooter on the...
The extremely red L dwarf ULAS J222711-004547 - dominated by dust
We report the discovery of a peculiar L dwarf from the United Kingdom Infrared Deep Sky Survey Large Area Survey, ULAS J222711-004547. The very red infrared...
The Faber-Jackson relation for early-type galaxies: dependence on the magnitude range
Aims: Previous studies have found that the coefficients and intrinsic dispersions of both the Kormendy relation and the Fundamental Plane depend on the...
The Faint "Heartbeats" of IGR J17091-3624: An Exceptional Black Hole Candidate
We report on the first 180 days of Rossi X-Ray Timing Explorer observations of the outburst of the black hole candidate IGR J17091-3624. This source exhibits a...
The far-infrared/radio correlation as probed by Herschel
We set out to determine the ratio, qIR, of rest-frame 8-1000-μm flux, SIR, to monochromatic radio flux, S1.4 GHz, for galaxies selected at far-infrared (IR) and...
