The Massive Star-forming Regions Omnibus X-ray Catalog, Second Installment [PDF]
, 2018 We present the second installment of the Massive Star-forming Regions (MSFRs) Omnibus X-ray Catalog (MOXC2), a compilation of X-ray point sources detected in Chandra/ACIS observations of 16 Galactic MSFRs and surrounding fields.

Depletion of Heavy Nitrogen in the Cold Gas of Star-forming Regions [PDF]
, 2018 We investigate nitrogen-isotope fractionation in forming and evolving molecular clouds using gas-ice astrochemical simulations. We find that the bulk gas can become depleted in heavy nitrogen (15N) due to the formation of 15N-enriched ices.

Physical properties and H-ionizing-photon production rates of extreme nearby star-forming regions [PDF]
Monthly notices of the Royal Astronomical Society, 2017 Measurements of the galaxy UV luminosity function at z 6 suggest that young stars hosted in low-mass star-forming galaxies produced the bulk of hydrogen-ionizing photons necessary to reionize the intergalactic medium (IGM) by redshift z ∼ 6. Whether star-

Disentangling the role of environmental processes in galaxy clusters
, 2012 In this work we present the results of a novel approach devoted to disentangle the role of the environmental processes affecting galaxies in clusters. This is based on the analysis of the NUV-r' distributions of a large sample of star-forming galaxies in

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.

On the distance to the Ophiuchus star‐forming region [PDF]
Astronomische Nachrichten, 2008 AbstractThe Ophiuchus molecular cloud complex has produced in Lynds 1688 the richest known embedded cluster within ∼300 pc of the Sun. Unfortunately, distance estimates to the Oph complex vary by nearly ∼40% (∼120–165 pc). Here I calculate a new independent distance estimate of 135±8 pc to this benchmark star‐forming region based on Hipparcos ...

Anomalous Microwave Emission from Star Forming Regions
Advances in Astronomy, 2013 The evidence for microwave emission from spinning dust grains has been strengthened considerably by its detection in a number of discrete astrophysical objects associated with star formation.

Star-Forming Regions near GRB 990123 [PDF]
, 1999 We reduced the Hubble Space Telescope Space Telescope Imaging Spectrograph images of the gamma-ray burst GRB 990123 that were obtained on 8-9 February 1999 and find V_0 = 25.36 +/- 0.10, which corresponds to a flux of 0.258 +/- 0.023 micro-Jy for the ...
