On the significance of the excess number of strong MgII absorbers observed towards Gamma-ray bursts
Sharon Rapoport, Christopher A. Onken, J. Stuart B. Wyithe +2
The number of strong (equivalent width > 1A) MgII absorbers observed towards Gamma-ray bursts (GRBs) has been found to be statistically larger than the number of strong absorbers t…
Testing the gravitational lensing explanation for the MgII problem in GRBs
Sharon Rapoport, Christopher A. Onken, Brian P. Schmidt +3
Sixty percent of gamma-ray bursts (GRBs) reveal strong MgII absorbing systems, which is a factor of ~2 times the rate seen along lines-of-sight to quasars. The discrepancy in the c…
The Extragalactic Distance Scale without Cepheids IV
Lachlan Hislop, Jeremy Mould, Brian Schmidt +7
The Cepheid period-luminosity relation is the primary distance indicator used in most determinations of the Hubble constant. The tip of the red giant branch (TRGB) is an alternativ…
