The ACS Virgo Cluster Survey consists of HST-ACS Advance Camera for Surveys) imaging for 100 early-type galaxies in the Virgo Cluster, observed in the F475W (~SDSS g) and F850LP...
Spectra from the HST GHRS instrument (processed by ESO and CADC) in the 1,100 - 3,300 Å range, resolution ~ 2,000, 25,000, and 80,000 (echelle), V_max ~ 18, 16, and 12...
The possibility of the Ly{beta} fluorescence mechanism being operational in classical Be (CBe) stars and thereby contributing to the strength of the OI{lambda}8446 line has been...
We performed the largest and most homogeneous spectroscopic survey of field RR Lyraes (RRLs). We secured ~6300 high-resolution (HR, R~35000) spectra for 143 RRLs (111...
