Testing 24 micron and Infrared Luminosity as Star Formation Tracers for Galactic Star Forming Regions [PDF]
, 2013 We have tested some relations for star formation rates used in extra-galactic studies for regions within the Galaxy. In nearby molecular clouds, where the IMF is not fully-sampled, the dust emission at 24 micron greatly underestimates star formation ...

The Effect of Local Galaxy Surface Density on Star Formation for HI selected galaxies [PDF]
, 2006 We present the result of investigations into two theories to explain the star formation rate-density relationship. For regions of high galaxy density, either there are fewer star forming galaxies, or galaxies capable of forming stars are present but some

Hydrogen Fluoride in High-Mass Star-forming Regions [PDF]
, 2012 Hydrogen fluoride has been established to be an excellent tracer of molecular hydrogen in diffuse clouds. In denser environments, however, the HF abundance has been shown to be approximately two orders of magnitude lower.

The use of extra-galactic star formation tracers on star forming regions in the Milky Way [PDF]
, 2016 We studied three groups of star forming clouds in the Milky Way: 5 clouds from Spitzer c2d Legacy survey, 10 clouds from Gould Belt survey, and 32 massive dense clumps.

UVIT Imaging of WLM: Demographics of Star-forming Regions in the Nearby Dwarf Irregular Galaxy [PDF]
Astronomical Journal, 2018 We present a study of star-forming regions and their demographics in the nearby dwarf irregular galaxy WLM using Ultraviolet Imaging Telescope (UVIT) multiband observations in three filters, F148W, N245M, and N263M.

Galaxy Interactions in Compact Groups II: abundance and kinematic anomalies in HCG 91c [PDF]
, 2015 Galaxies in Hickson Compact Group 91 (HCG 91) were observed with the WiFeS integral field spectrograph as part of our ongoing campaign targeting the ionized gas physics and kinematics inside star forming members of compact groups.

Seeds Of Life In Space (SOLIS): The Organic Composition Diversity at 300–1000 au Scale in Solar-type Star-forming Regions [PDF]
, 2017 Complex organic molecules have been observed for decades in the interstellar medium. Some of them might be considered as small bricks of the macromolecules at the base of terrestrial life.

THE FIRST DETECTIONS OF THE KEY PREBIOTIC MOLECULE PO IN STAR-FORMING REGIONS [PDF]
Proceedings of the International Astronomical Union, 2016 Phosphorus is a crucial element in biochemistry, in particular the P−O bond, which is key in the formation of the backbone of deoxyribonucleic acid. So far, PO has only been detected toward the envelope of evolved stars, but never toward star-forming ...
