Low-column density HVC and IVC gas in the halo of the Milky Way
N. Ben Bekhti, P. Richter, M. T. Murphy
Recent studies of the circumgalactic gaseous environment of the Milky Way have concentrated on the distribution, chemical composition, and physical properties of the most massive n…
Strong Limit on a Variable Proton-to-Electron Mass Ratio from Molecules in the Distant Universe
Michael T. Murphy, Victor V. Flambaum, Sebastien Muller +1
The Standard Model of particle physics assumes that the so-called fundamental constants are universal and unchanging. Absorption lines arising in molecular clouds along quasar sigh…
Halo Gas Cross Sections And Covering Fractions of MgII Absorption Selected Galaxies
G. G. Kacprzak, C. W. Churchill, C. C. Steidel +1
We examine halo gas cross sections and covering fractions, f_c, of intermediate redshift MgII absorption selected galaxies. We computed statistical absorber halo radii, R_x, using…
Comment on "Limits on the Time Variation of the Electromagnetic Fine-Structure Constant in the Low Energy Limit from Absorption Lines in the Spectra of Distant Quasars"
Michael T. Murphy, John K. Webb, Victor V. Flambaum
In their Letter [Phys. Rev. Lett. 92, 121302 (2004)] (also [Astron. Astrophys. 417, 853 (2004)]), Srianand et al. analysed optical spectra of heavy-element species in 23 absorption…
The host galaxies of strong CaII QSO absorption systems at z<0.5
Berkeley J. Zych, Michael T. Murphy, Max Pettini +3
We present new imaging and spectroscopic observations of the fields of five QSOs with very strong intervening CaII absorption systems at redshifts z<0.5 selected from the Sloan Dig…
