[C ii] Spectral Mapping of the Galactic Wind and Starbursting Disk of M82 with SOFIA

open access: yesThe Astrophysical Journal, 2023
M82 is an archetypal starburst galaxy in the local Universe. The central burst of star formation, thought to be triggered by M82's interaction with other members in the M81 group, is driving a multiphase galaxy-scale wind away from the plane of the disk ...

The PhotoDissociation Region Toolbox: Software and Models for Astrophysical Analysis

open access: yesThe Astronomical Journal, 2022
The PhotoDissociation Region Toolbox provides comprehensive, easy-to-use, public software tools and models that enable an understanding of the interaction of the light of young, luminous, massive stars with the gas and dust in the Milky Way and in other ...

A multifrequency study of the active star forming complex NGC6357. I. Interstellar structures linked to the open cluster Pis24 [PDF]

open access: yes, 2011
We investigate the distribution of the gas (ionized, neutral atomic and molecular), and interstellar dust in the complex star forming region NGC6357 with the goal of studying the interplay between the massive stars in the open cluster Pis24 and the ...

Dust and gas in star-forming complexes in NGC 3351, NGC 5055, and NGC 5457

open access: yesOpen Astronomy, 2023
We present a study of the interstellar medium parameters in star-forming complexes (SFCs) in NGC 3351, NGC 5055, and NGC 5457 galaxies. This study concludes our previous investigations of gas and dust in a number of spiral galaxies.

The effect of ISM turbulence on the gravitational instability of galactic discs

open access: yes, 2012
We investigate the gravitational instability of galactic discs, treating stars and cold interstellar gas as two distinct components, and taking into account the phenomenology of turbulence in the interstellar medium (ISM), i.e.

Relative In-flight Response of IBEX-Lo to Interstellar Neutral Helium Atoms

open access: yesThe Astrophysical Journal Supplement Series, 2023
The IBEX-Lo instrument on the Interstellar Boundary Explorer (IBEX) mission measures interstellar neutral (ISN) helium atoms. The detection of helium atoms is made through negative hydrogen (H ^− ) ions sputtered by helium atoms from the IBEX-Lo’s ...

Spatial distribution of interstellar gas in the innermost 3 kpc of our Galaxy

open access: yes, 2007
We review the present observational knowledge on the spatial distribution and the physical state of the different (molecular, atomic and ionized) components of the interstellar gas in the innermost 3 kpc of our Galaxy -- a region which we refer to as the

Are Giant Planets Forming Around HR 4796A? [PDF]

open access: yes, 2003
We have obtained FUSE and HST STIS spectra of HR 4796A, a nearby 8 Myr old main sequence star that possesses a dusty circumstellar disk whose inclination has been constrained from high resolution near-infrared observations to be ~17 deg from edge-on.

Filtration of Interstellar Neutral Helium by Elastic and Charge Exchange Collisions in Heliospheric Boundaries

open access: yesThe Astrophysical Journal, 2023
Interstellar neutral (ISN) helium atoms penetrating the heliosphere are used to find the flow velocity and temperature of the very local interstellar medium near the heliosphere.

Multiphase turbulent interstellar medium: some recent results from radio astronomy

open access: yes, 2015
The radio frequency 1.4 GHz transition of the atomic hydrogen is one of the important tracers of the diffuse neutral interstellar medium. Radio astronomical observations of this transition, using either a single dish telescope or an array interferometer,
