JWST Reveals Star Formation Across a Spiral Arm in M33
J. Peltonen, Erik Rosolowsky, Thomas G. Williams +13
Young stellar objects (YSOs) are the gold standard for tracing star formation in galaxies but have been unobservable beyond the Milky Way and Magellanic Clouds. But that all change…
A Two-Component Probability Distribution Function Describes the mid-IR Emission from the Disks of Star-Forming Galaxies

The low- rotational transitions of CO are commonly used to trace the distribution of molecular gas in galaxies. Their ratios are sensitive to excitation and physical cond…
The WISDOM of power spectra: how the galactic gravitational potential impacts a galaxy's central gas reservoir in simulations and observations
Jindra Gensior, Timothy A. Davis, Martin Bureau +4
Observations indicate that the central gas discs are smoother in early-type galaxies than their late-type counterparts, while recent simulations predict that the dynamical suppress…

M. Querejeta, J. Pety, A. Schruba +31
We present a new wide-field 10.75 x 10.75 arcmin^2 (~11x11 kpc^2), high-resolution (theta = 3.6" ~ 60 pc) NOEMA CO(1-0) survey of the very nearby (d=3.45 Mpc) spiral galaxy IC 342.…
Where do stars explode in the ISM? -- The distribution of dense gas around evolved massive stars in M33
Sumit K. Sarbadhicary, Jordan Wagner, Eric W. Koch +27
The effect of supernovae (SNe) on star-formation in the interstellar medium (ISM) depends sensitively on where SNe explode with respect to ISM clouds. Observationally, SN ISM envir…
Investigating the Drivers of Electron Temperature Variations in HII Regions with Keck-KCWI and VLT-MUSE
Ryan J. Rickards Vaught, Karin M. Sandstrom, Francesco Belfiore +12
HII region electron temperatures are a critical ingredient in metallicity determinations and recent observations reveal systematic variations in the temperatures measured using dif…
Quantifying the energy balance between the turbulent ionised gas and young stars
Oleg V. Egorov, Kathryn Kreckel, Simon C. O. Glover +19
We investigate the ionised gas morphology, excitation properties, and kinematics in 19 nearby star-forming galaxies from the PHANGS-MUSE survey. We directly compare the kinetic ene…
WISDOM Project -- XVII. Beam-by-beam Properties of the Molecular Gas in Early-type Galaxies
Thomas G. Williams, Martin Bureau, Timothy A. Davis +9
We present a study of the molecular gas of seven early-type galaxies with high angular resolution data obtained as part of the mm-Wave Interferometric Survey of Dark Object Masses…
A constant NH(1-0)-to-HCN(1-0) ratio on kiloparsec scales

Nitrogen hydrides such as NH and NH are widely used by Galactic observers to trace the cold dense regions of the interstellar medium. In external galaxies, because of l…
Star Cluster Classification using Deep Transfer Learning with PHANGS-HST
Stephen Hannon, Bradley C. Whitmore, Janice C. Lee +17
Currently available star cluster catalogues from HST imaging of nearby galaxies heavily rely on visual inspection and classification of candidate clusters. The time-consuming natur…
A fundamental plane of black hole accretion at millimetre wavelengths
Ilaria Ruffa, Timothy A. Davis, Jacob S. Elford +11
We report the discovery of the ``mm fundamental plane of black-hole accretion'', which is a tight correlation between the nuclear 1 mm luminosity (), the intrinsic $…
On the Tremaine-Weinberg method: how much can we trust gas tracers to measure pattern speeds?
Olga Borodina, Thomas G. Williams, Mattia C. Sormani +2
Pattern speeds are a fundamental parameter of the dynamical features (e.g. bars, spiral arms) of a galaxy, setting resonance locations. Pattern speeds are not directly observable,…
Calibrating mid-infrared emission as a tracer of obscured star formation on HII-region scales in the era of JWST
