Observational Signatures of Cosmic-Ray Interactions in Molecular Clouds
• Physics
• 2021
We investigate ionization and heating of gas in the dense, shielded clumps/cores of molecular clouds bathed by an influx of energetic, charged cosmic rays (CRs). These molecular clouds have complexExpand
Interaction of cosmic rays with molecular clouds
• Physics
• 2018
Abstract We analyze interaction of fast charged particles with Galactic molecular clouds. As a results of energy losses inside the clouds, a particle flux, converging to the cloud, is formed in theExpand

• Physics
• 2017
We acknowledge support from the Aryabhatta Research Institute of Observational Sciences and Lulin Observatory concerning the data collected using AIMPOL and TRIPOL. This research was conducted inExpand
Cosmic-ray propagation in the bi-stable interstellar medium
• Physics
• Astronomy & Astrophysics
• 2019
Context. Cosmic rays propagate through the galactic scales down to the smaller scales at which stars form. Cosmic rays are close to energy equipartition with the other components of the interstellarExpand
Cosmic rays, γ-rays, and neutrinos in the starburst nuclei of Arp 220
• Physics
• 2015
The cores of Arp 220, the closest ultra-luminous infrared starburst galaxy, provide an opportunity to study interactions of cosmic rays under extreme conditions. In this paper, we model theExpand
Multiwavelength Polarimetry of the Filamentary Cloud IC 5146. II. Magnetic Field Structures
The IC5146 cloud is a nearby star-forming region in Cygnus, consisting of molecular gas filaments in a variety of evolutionary stages. We used optical and near-infrared polarization data toward theExpand
A COSMIC-RAY-DOMINATED INTERSTELLAR MEDIUM IN ULTRA LUMINOUS INFRARED GALAXIES: NEW INITIAL CONDITIONS FOR STAR FORMATION
The high-density star formation typical of the merger/starburst events that power the large IR luminosities of ultraluminous infrared galaxies (ULIRGs) (L IR(8-1000 μm) 1012 L ☉) throughout theExpand
Limits on the cosmic-ray ionization rate toward massive young stars
Recent models of the envelopes of seven massive protostars are used to analyze observations of H3+ infrared absorption and H13CO+ submillimeter emission lines toward these stars, and to constrain theExpand
Equipartition and cosmic ray energy densities in central molecular zones of starbursts
• Physics
• 2016
The energy densities in magnetic fields and cosmic rays (CRs) in galaxies are often assumed to be in equipartition, allowing for an indirect estimate of the magnetic field strength from the observedExpand
JCMT BISTRO Survey: Magnetic Fields within the Hub-filament Structure in IC 5146
We present the 850 $\mu$m polarization observations toward the IC5146 filamentary cloud taken using the SCUBA-2 POL-2, mounted on the JCMT, as part of the B-fields In STar forming RegionsExpand
