Characterizing the Circumgalactic Medium of Nearby Galaxies with HST/COS and HST/STIS Absorption-Line Spectroscopy
John T. Stocke, Brian A. Keeney, Charles W. Danforth +5
The Circumgalactic Medium (CGM) of late-type galaxies is characterized using UV spectroscopy of 11 targeted QSO/galaxy pairs at z < 0.02 with the Hubble Space Telescope Cosmic Orig…
WR 120bb and WR 120bc: a pair of WN9h stars with possibly interacting circumstellar shells
Sonja Burgemeister, Vasilii V. Gvaramadze, Guy S. Stringfellow +3
Two optically obscured Wolf-Rayet (WR) stars have been recently discovered by means of their infrared (IR) circumstellar shells, which show signatures of interaction with each othe…
The LOFAR radio environment
A. R. Offringa, A. G. de Bruyn, S. Zaroubi +93
Aims: This paper discusses the spectral occupancy for performing radio astronomy with the Low-Frequency Array (LOFAR), with a focus on imaging observations. Methods: We have analys…
The Scale of the Problem : Recovering Images of Reionization with GMCA
Emma Chapman, Filipe B. Abdalla, J. Bobin +8
The accurate and precise removal of 21-cm foregrounds from Epoch of Reionization redshifted 21-cm emission data is essential if we are to gain insight into an unexplored cosmologic…
On the Significance of Absorption Features in HST/COS Data
Brian A. Keeney, Charles W. Danforth, John T. Stocke +2
We present empirical scaling relations for the significance of absorption features detected in medium resolution, far-UV spectra obtained with the Cosmic Origins Spectrograph (COS)…
Precision Measurement of The Most Distant Spectroscopically Confirmed Supernova Ia with the Hubble Space Telescope
D. Rubin, R. A. Knop, E. Rykoff +25
We report the discovery of a redshift 1.71 supernova in the GOODS North field. The Hubble Space Telescope (HST) ACS spectrum has almost negligible contamination from the host or ne…
