GALEX observations of quasar variability in the ultraviolet
Barry Y. Welsh, Jonathan M. Wheatley, James D. Neill
Using archival observations recorded over a 5+ year timeframe with the NASA Galaxy Evolution Explorer (GALEX) satellite, we present a study of the ultraviolet (UV) variability of 4…
Detection of highly ionized CIV gas within the Local Cavity
Barry Y. Welsh, Jonathan Wheatley, Oswald H. W. Siegmund +1
We present high resolution (R = 114,000) ultraviolet measurements of the interstellar absorption line profiles of the CIV (1550 A) high ionization doublet recorded towards the near…
GALEX ultraviolet observations of stellar variability in the Hyades and Pleiades clusters
S. E. Browne, B. Y. Welsh, J. M. Wheatley
We present GALEX near ultraviolet (NUV:1750 - 2750A) and far ultraviolet (FUV: 1350 - 1750A) imaging observations of two 1.2 degree diameter fields in the Hyades and Pleiades open…
High resolution NaI and CaII absorption observations towards M13, M15 and M33
B. Y. Welsh, J. M. Wheatley, R. Lallement
We present high resolution (R = 60,000) measurements of the NaI D1 and D2 (5890 A) and CaII K (3933 A) interstellar absorption line profiles recorded towards several post-AGB stars…
The Second Galex Ultraviolet Variability (GUVV-2) Catalog
Jonathan M. Wheatley, Barry Y. Welsh, Stanley E. Browne
We present the second Galaxy Evolution Explorer (GALEX) Ultraviolet Variability (GUVV-2) Catalog that contains information on 410 newly discovered time-variable sources gained thro…
GALEX high time-resolution ultraviolet observations of dMe flare events
B. Y. Welsh, J. M. Wheatley, S. E. Browne +8
We present near ultraviolet (NUV:1750 - 2800Å) and far ultraviolet (FUV: 1350 - 1750Å) light-curves for flares on 4 nearby dMe-type stars (GJ 3685A, CR Dra, AF Psc and SDSS J084425…
