Evidence for Correlated Titanium and Deuterium Depletion in the Galactic ISM
abundances abundances

2014/12/24
Current measurements indicate that the deuterium abundance in diffuse interstellar gas varies spatially by a factor of ~4 among sightlines extending beyond the Local Bubble. One plausible explanation ...
The opacity of spiral galaxy disks. VIII. Structure of the cold ISM
galaxies ISM
font style='font-size:12px;'>
2014/12/23
The quantity of dust in a spiral disk can be estimated using the dust's typical emission or the extinction of a known source. In this paper we compare two techniques, one based on emission and one on ...
A Systematic Study of the Stellar Populations and ISM in Galaxies out to the Virgo Cluster

2014/12/22
We present a compelling case for a systematic and comprehensive study of the resolved and unresolved stellar populations, ISM, and immediate environments of galaxies throughout the local volume, defin...

We present a compelling case for a systematic and comprehensive study of the resolved and unresolved stellar populations, ISM, and immediate environments of galaxies throughout the local volume, defin...
Classifying structures in the ISM with Support Vector Machines: the G16.05-0.57 supernova remnant
Classifying structures Support Vector Machines supernova remnant
font style='font-size:12px;'>
2011/10/20
We apply Support Vector Machines -- a machine learning algorithm -- to the task of classifying structures in the Interstellar Medium. As a case study, we present a position-position velocity data cube...
A Detailed Study of the Molecular and Atomic Gas Toward the γ-ray SNR RX J1713.7-3946: Spatial TeV γ-ray and ISM Gas Correspondence
McClure-Griffi ths G. Rowel T. Inoue S. Inutsuka A. Kawamura
font style='font-size:12px;'>
2011/9/27
RX J1713.7-3946 is the most remarkable TeV {\gamma}-ray SNR which emits {\gamma}-rays in the highest energy range 10-100 TeV. We made a combined analysis of CO and HI in the SNR and derived the total ...
The Evolution of the Large-scale ISM: Bubbles, Superbubbles and Non-Equilibrium Ionization
the Large-scale ISM Bubbles Superbubbles
font style='font-size:12px;'>
2011/1/11
The ISM, powered by SNe, is turbulent and permeated by a magnetic field (with a mean and a turbulent component). It constitutes a frothy medium that is mostly out of equilibrium and is ram pressure do...
ISM enrichment and local pollution in dwarf galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Galaxy Astrophysics (astro-ph.GA)
font style='font-size:12px;'>
2010/12/28
The fate of metals after they are released in starburst episodes is still unclear. What phases of the interstellar medium are involved, in which timescales?
Positron annihilation spectrum from the Galactic Centre region observed by SPI/INTEGRAL, revisited: annihilation in a cooling ISM?
High Energy Astrophysical Phenomena (astro-ph.HE)
font style='font-size:12px;'>
2010/12/24
We analyse SPI/INTEGRAL data on the 511 keV line from the Galactic Centre, accumulated over ~6 years of observations.
