The EDIBLES survey IV. Cosmic ray ionization rates in diffuse clouds from near-ultraviolet observations of interstellar OH

Xavier L. Bacalla, Harold Linnartz, Nick L. J. Cox +6

We report cosmic ray ionization rates towards ten reddened stars studied within the framework of the EDIBLES (ESO Diffuse Interstellar Bands Large Exploration Survey) program, usin…

A Catalogue of Galactic Supernova Remnants in the far-infrared: revealing ejecta dust in pulsar wind nebulae

Hannah Chawner, Ken Marsh, Mikako Matsuura +7

We search for far-infrared (FIR) counterparts of known supernova remnants (SNRs) in the Galactic plane (10 deg <| l |< 60 deg) at 70-500 micron using the Herschel Infrared Galactic…

SOFIA FIFI-LS Observations of Sgr B1: Ionization Structure and Sources of Excitation

Janet P. Simpson, Sean W. J. Colgan, Angela S. Cotera +2

The current paradigm of Galactic Center (GC) gas motions and star formation envisions sequential star formation in streams of gas as they pass near the supermassive black hole, Sgr…

PAHs and star formation in the HII regions of nearby galaxies M83 and M33

A. Maragkoudakis, N. Ivkovich, E. Peeters +3

We present mid-infrared (MIR) spectra of HII regions within star-forming galaxies M83 and M33. Their emission features are compared with Galactic and extragalactic HII regions, HII…

Near-Infrared Spectroscopy of SN 2017eaw in 2017: Carbon Monoxide and Dust Formation in a Type II-P Supernova

J. Rho, T. R. Geballe, D. P. K. Banerjee +3

The origin of dust in the early Universe has been the subject of considerable debate. Core-collapse supernovae (ccSNe), which occur several million years after their massive progen…

The High Mass Slope of the IMF

Antonio Parravano, David Hollenbach, Christopher F. McKee

Recent papers have found that the inferred slope of the high-mass ( M) IMF for field stars in the solar vicinity has a larger value () than the slopes (…

The EDIBLES survey III. C2-DIBs and their profiles

M. Elyajouri, R. Lallement, N. L. J. Cox +6

The so-called C2-DIBs are a class of very weak bands that fall in the blue part of the optical spectrum and are associated with high column densities of the C2 molecule. DIB profil…

Spitzer Infrared Spectrograph Observations of the Galactic Center: Quantifying the Extreme Ultraviolet/so ft X-ray fluxes

Janet P. Simpson

It has long been shown that the extreme ultraviolet spectrum of the ionizing stars of H II regions can be estimated by comparing the observed line emission to detailed models. In t…

Polycyclic aromatic hydrocarbon emission toward the Galactic bulge

Matthew J. Shannon, Els Peeters, Jan Cami +1

We examine polycyclic aromatic hydrocarbon (PAH), dust and atomic/molecular emission toward the Galactic bulge using Spitzer Space Telescope observations of four fields: C32, C35,…

High-resolution IR absorption spectroscopy of polycyclic aromatic hydrocarbons in the 3 micron region: role of hydrogenation and alkylation

E. Maltseva, C. J. Mackie, A. Candian +6

Aims. We aim to elucidate the spectral changes in the 3 micron region that result from chemical changes in the molecular periphery of polycyclic aromatic hydrocarbons (PAHs) with e…
