The importance of radiative pumping on the emission of the H_2O submillimeter lines in galaxies
Eduardo González-Alfonso, Jacqueline Fischer, Javier R. Goicoechea +3
H_2O submillimeter emission is a powerful diagnostic of the molecular interstellar medium in a variety of sources, including low- and high-mass star forming regions of the Milky Wa…
A proto-pseudobulge in ESO 320-G030 fed by a massive molecular inflow driven by a nuclear bar
Eduardo González-Alfonso, Miguel Pereira-Santaella, Jacqueline Fischer +10
Galaxies with nuclear bars are believed to efficiently drive gas inward, generating a nuclear starburst and possibly an active galactic nucleus (AGN). We confirm this scenario for…
Outflowing OH in Markarian 231: the ionization rate of the molecular gas
E. González-Alfonso, J. Fischer, S. Bruderer +6
The oxygen-bearing molecular ions OH+, H2O+, and H3O+ are key species that probe the ionization rate of (partially) molecular gas that is ionized by X-rays and cosmic rays permeati…
Molecular outflows in local ULIRGs: energetics from multi-transition OH analysis
E. González-Alfonso, J. Fischer, H. W. W. Spoon +11
We report on the energetics of molecular outflows in 14 local Ultraluminous Infrared Galaxies (ULIRGs) that show unambiguous outflow signatures (P-Cygni profiles or high-velocity a…
A wide-band, active antenna system for long wavelength radio astronomy
Brian C. Hicks, Nagini Paravastu-Dalal, Kenneth P. Stewart +9
We describe an "active" antenna system for HF/VHF (long wavelength) radio astronomy that has been successfully deployed 256-fold as the first station (LWA1) of the planned Long Wav…
First Light for the First Station of the Long Wavelength Array
G. B. Taylor, S. W. Ellingson, N. E. Kassim +32
The first station of the Long Wavelength Array (LWA1) was completed in April 2011 and is currently performing observations resulting from its first call for proposals in addition t…
