Eclipsing binary stars in the Large and Small Magellanic Clouds from the MACHO project: The Sample
Lorenzo Faccioli, Charles Alcock, Kem Cook +3
We present a new sample of 4634 eclipsing binary stars in the Large Magellanic Cloud (LMC), expanding on a previous sample of 611 objects and a new sample of 1509 eclipsing binary…
The Keck+Magellan Survey for Lyman Limit Absorption I: The Frequency Distribution of Super Lyman Limit Systems
John M O'Meara, Jason X. Prochaska, Scott Burles +3
We present the results of a survey for super Lyman limit systems (SLLS; defined to be absorbers with 19.0 <= log(NHI) <= 20.3 cm^-2) from a large sample of high resolution spectra…
The Deuterium to Hydrogen Abundance Ratio Towards the QSO SDSS1558-0031
John M. O'Meara, Scott Burles, Jason X. Prochaska +3
We present a measurement of the D/H abundance ratio in a metal-poor damped Lyman alpha (DLA) system along the sightline of QSO SDSS1558-0031. The DLA system is at redshift z = 2.70…
The Metal-Strong Damped Lyman-alpha Systems
Stéphane Herbert-Fort, Jason X. Prochaska, Miroslava Dessauges-Zavadsky +4
We have identified a metal-strong (logN(Zn+) > 13.15 or logN(Si+) > 15.95) DLA (MSDLA) population from an automated quasar (QSO) absorber search in the Sloan Digital Sky Survey Dat…
Super-Solar Super Lyman Limit Systems
Jason X. Prochaska, John M. O'Meara, Stephane Herbert-Fort +3
We present abundance measurements for two super Lyman Limit systems (SLLS; quasar absorption line systems with 10^19 cm^-2 < N_HI < 10^20.3 cm^-2) selected from a set of metal-stro…
On the Incidence of Strong MgII Absorbers Along GRB Sightlines
G. E. Prochter, J. X. Prochaska, H. -W. Chen +7
We report on a survey for strong (rest equivalent width W_r >= 1A), intervening MgII systems along the sightlines to long-duration gamma-ray bursts (GRBs). The GRB spectra which co…
