On the integrated continuum radio spectrum of supernova remnant W44 (G34.7-0.4): new insights from Planck [PDF]
Serbian Astronomical Journal, 2015 In this paper, the integrated continuum radio spectrum of supernova remnant (SNR) W44 was analyzed up to 70 GHz, testing the different emission models that can be responsible for its particular shape.

Gone with the heat: a fundamental constraint on the imaging of dust and molecular gas in the early Universe [PDF]
Royal Society Open Science, 2016 Images of dust continuum and carbon monoxide (CO) line emission are powerful tools for deducing structural characteristics of galaxies, such as disc sizes, H2 gas velocity fields and enclosed H2 and dynamical masses. We report on a fundamental constraint

FORCASTing the Spectroscopic Dust Properties of the WC+O Binary WR 137 with SOFIA
The Astrophysical Journal, 2023 WR 137 (HD 192641) is a binary system consisting of a carbon-rich Wolf–Rayet (W-R) star and an Oe companion star in a 13 yr orbit. Near periastron, the winds of the two stars collide and form carbonaceous dust.

Star Formation and Molecular Gas Diagnostics with Mid- and Far-infrared Emission
The Astrophysical Journal, 2023 With the start of JWST observations, mid-infrared (MIR) emission features from polycyclic aromatic hydrocarbons (PAHs), H _2 rotational lines, fine structure lines from ions, and dust continuum will be widely available tracers of gas and star formation ...

The radio-infrared correlation in galaxies [PDF]
, 2009 The radio-infrared correlation was explained as a direct and linear relationship between star formation and IR emission. However, one fact making the IR-star formation linkage less obvious is that the IR emission consists of at least two emission ...

On the nature of the transition disk around LkCa 15 [PDF]
, 2012 We present CARMA 1.3 mm continuum observations of the T Tauri star LkCa 15,which resolve the circumstellar dust continuum emission on angular scales between 0.2-3 arcsec, corresponding to 28-420 AU at the distance of the star.
