A low H I column density filament in NGC 2403 : signature of interaction or accretion
(2014-09-25)
Observed H i accretion around nearby galaxies can only account for a fraction of the gas supply needed to sustain the currently observed star formation rates. It is possible that additional accretion occurs in the form of ...
The Radio Continuum-Star Formation Rate Relation in WSRT SINGS Galaxies
(2014-04-02)
We present a study of the spatially resolved radio continuum–star formation rate (RC–SFR) relation using stateof-the-art star formation tracers in a sample of 17 THINGS galaxies. We use SFR surface density (ΣSFR) maps ...
Shock Excited Molecules in NGC 1266 : ULIRG Conditions at the Center of a Bulge-dominated Galaxy
(2013-12)
We investigate the far infrared (IR) spectrum of NGC 1266, a S0 galaxy that contains a massive reservoir of highly excited molecular gas. Using the Herschel Fourier Transform Spectrometer, we detect the 12CO ladder up to ...
Carbon monoxide in clouds at low metallicity in the dwarf irregular galaxy WLM
(2013-03-27)
Carbon monoxide (CO) is the primary tracer for interstellar clouds where stars form, but it has never been detected in galaxies in which the oxygen abundance relative to hydrogen is less than 20 per cent of that of the ...
CO in late-type galaxies within the central region of Abell 1367
(2013-02)
We present 12CO (J = 1→ 0) and 12CO (J = 2 →1) spectra for 19 bright, late–type galaxies (spirals) in the central region of the galaxy cluster Abell 1367 (z = 0.02) from observations make with the IRAM 30–m telescope. All ...
NGC 2207/IC 2163 : A Grazing Encounter with Large-scale Shocks
(2012-11)
Radio continuum, Spitzer infrared, optical, and XMM-Newton X-ray and ultraviolet observations (UVW1 and UVM2) are used to study large-scale shock fronts, young star complexes, and the galactic nuclei in the interacting ...
Little Things
(2012-11)
We present LITTLE THINGS (Local Irregulars That Trace Luminosity Extremes, The H I Nearby Galaxy Survey), which is aimed at determining what drives star formation in dwarf galaxies. This is a multi-wavelength survey of 37 ...
