CO luminosity functions for far-infrared- and B-band-selected galaxies and the first estimate for Omega(H I+H2)
surveys molecules
2014/12/24
We derive a nonparametric CO luminosity function using an FIR- and an optical B-band-selected sample of the galaxies included in the FCRAO Extragalactic CO Survey. The FIR-selected sample is defined u...
When sticking influences H2 formation
ISM: dust, extinction – ISM: molecules – ISM: abundances
2011/10/20
Aims. Interstellar dust grains, because of their catalytic properties, are crucial to the formation of H2, the most abundant molecule in the Universe. The formation of molecular hydrogen strongly depe...
A survey for near-infrared H2 emission in Herbig Ae/Be stars: emission from the outer disks of HD 97048 and HD 100546
circumstellar matter, stars – pre-main-sequence, emission-line, protoplanetary disks
2011/9/30
We report on a sensitive search for H2 1-0 S(1), 1-0 S(0) and 2-1 S(1) ro-vibrational emission at 2.12, 2.22 and 2.25 micron in a sample of 15 Herbig Ae/Be stars employing CRIRES, the ESO-VLT near-inf...
The deeply obscured AGN of NGC4945 I. Spitzer-IRS maps of [Ne V], [Ne II], H2 0-0 S(1), S(2), and other tracers
Galaxies:active – Galaxies:nuclei – Galaxies:individual:NGC 4945 – ISM:lines and bands
2011/9/27
The nearly edge-on galaxy NGC4945 is one of the closest galaxies where an AGN and starburst coexist, and is one of the brightest sources at 100 keV. Near and mid-infrared spectroscopy have shown very ...
How Universal is the SFR - H2 Relation?
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
2010/12/27
It is a well established empirical fact that the surface density of the star formation rate, Sigma_SFR, strongly correlates with the surface density of molecular hydrogen, Sigma_H2, at least when aver...
Spitzer Mapping of PAHs and H2 in Photodissociation Regions
Galaxy Astrophysics (astro-ph.GA)
2010/12/22
The mid-infrared (MIR) spectra of dense photodissociation regions (PDRs) are typically dominated by emission from polycyclic aromatic hydrocarbons (PAHs) and the lowest pure rotational states of molec...
