Anatomy of a post-starburst minor merger: a multi-wavelength WFC3 study of NGC 4150
R. Mark Crockett, Sugata Kaviraj, Joseph I. Silk +22
(Abridged) We present a spatially-resolved near-UV/optical study of NGC 4150, using the Wide Field Camera 3 (WFC3) on board the Hubble Space Telescope. Previous studies of this ear…
Near-Ultraviolet Properties of a Large Sample of Type Ia Supernovae as Observed with the Swift UVOT
Peter A. Milne, Peter J. Brown, Peter W. A. Roming +15
We present ultraviolet (UV) and optical photometry of 26 Type Ia supernovae (SNe~Ia) observed from March 2005 to March 2008 with the NASA {\it Swift} Ultraviolet and Optical Telesc…
The Absolute Magnitudes of Type Ia Supernovae in the Ultraviolet
Peter J. Brown, Peter W. A. Roming, Peter Milne +19
We examine the absolute magnitudes and light-curve shapes of 14 nearby(redshift z = 0.004--0.027) Type Ia supernovae (SNe~Ia) observed in the ultraviolet (UV) with the Swift Ultrav…
TANAMI: Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry I. First-Epoch 8.4 GHz Images
Roopesh Ojha, Matthias Kadler, Moritz Böck +24
We introduce the TANAMI program (Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry) which is monitoring an initial sample of 43 extragalactic jets located…
The December 2009 gamma-ray flare of 3C 454.3: the multifrequency campaign
L. Pacciani, V. Vittorini, M. Tavani +81
During the month of December, 2009 the blazar 3C 454.3 became the brightest gamma-ray source in the sky, reaching a peak flux F ~2000E-8 ph/cm2/s for E > 100 MeV. Starting in Novem…
Cold dust clumps in dynamically hot gas
S. Kim, E. Kwon, S. C. Madden +27
We present clumps of dust emission from Herschel observations of the Large Magellanic Cloud (LMC) and their physical and statistical properties. We catalog cloud features seen in t…
