Detection of diffuse HI emission in the circumgalactic medium of NGC891 and NGC4565 -- II
Sanskriti Das, Mary Rickel, Adam Leroy +6
We probe the neutral circumgalactic medium (CGM) along the major axes of NGC891 and NGC4565 in 21-cm emission out to kpc using the Green Bank Telescope (GBT), extendin…
Closing the Gap between Observed Low-Mass Galaxy HI Kinematics and CDM Predictions
Amy Sardone, Annika H. G. Peter, Alyson M. Brooks +1
Testing the standard cosmological model (CDM) at small scales is challenging. Galaxies that inhabit low-mass dark matter halos provide an ideal test bed for dark matter models b…
Kinematic analysis of the super-extended HI disk of the nearby spiral galaxy M83
Cosima Eibensteiner, Frank Bigiel, Adam K. Leroy +33
We present new HI observations of the nearby massive spiral galaxy M83, taken with the VLA at angular resolution ( pc) of an extended (1.5 deg…
Star Formation Laws and Efficiencies across 80 Nearby Galaxies
Jiayi Sun, Adam K. Leroy, Eve C. Ostriker +37
We measure empirical relationships between the local star formation rate (SFR) and properties of the star-forming molecular gas on 1.5 kpc scales across 80 nearby galaxies. These r…
Kpc-scale properties of dust temperature in terms of dust mass and star formation activity
I-Da Chiang, Hiroyuki Hirashita, Jeremy Chastenet +7
We investigate how the dust temperature is affected by local environmental quantities, especially dust surface density (), dust-to-gas ratio (D/G) and interstellar…
PHANGS-JWST First Results: Mid-infrared emission traces both gas column density and heating at 100 pc scales
Adam K. Leroy, Karin Sandstrom, Erik Rosolowsky +48
We compare mid-infrared (mid-IR), extinction-corrected H, and CO (2-1) emission at 70--160 pc resolution in the first four PHANGS-JWST targets. We report correlation strengths,…
PHANGS-JWST First Results: Variations in PAH Fraction as a Function of ISM Phase and Metallicity
Jérémy Chastenet, Jessica Sutter, Karin Sandstrom +26
We present maps tracing the fraction of dust in the form of polycyclic aromatic hydrocarbons (PAHs) in IC 5332, NGC 628, NGC 1365, and NGC 7496 from JWST/MIRI observations. We trac…
