Quantifying the decline in CO(2-1) intensity around PHANGS-HST star clusters: Constraints on molecular gas dispersal, stellar feedback, and cluster formation efficiency
Hao He, Adam K. Leroy, Erik Rosolowsky +37
We combine the largest survey of star clusters in nearby galaxies to-date, PHANGS-HST, with maps of molecular gas maps from PHANGS-ALMA to constrain the efficiency of cluster forma…
A Comparative Systems-Engineering Framework for RFI Coexistence in Radio Astronomy and Aviation Safety Systems
Simthembile Dlamini
Radio astronomy and aviation safety systems occupy opposite ends of the signal-power spectrum, yet both depend on the same finite resource and are increasingly squeezed by commerci…
The PHANGS-Hα survey. Ground-based narrow-band imaging of nearby star-forming galaxies
Alessandro Razza, Guillermo A. Blanc, Brent Groves +36
We present PHANGS-Hα, a narrow-band imaging survey that maps Hα emission over a sample of 65 nearby massive star-forming galaxies. The data were obtained using the MPG-ESO 2.2-mete…
The lifetime of 100,000 molecular clouds in the nearby Universe
Z. Bazzi, M. I. N. Kobayashi, D. Colombo +25
Multiple mechanisms are proposed for the formation of giant molecular clouds (GMCs), from gravitational free-fall caused by self-gravity to stellar feedback-driven gas compression.…
Fast Radio Burst Dispersion Measure--Timing Cross-Correlations: Bias Self-Calibration and Primordial Non-Gaussianity Constraints
Simthembile Dlamini
Fast Radio Bursts (FRBs) carry fossil information about non-Gaussianity generated during inflation. This primordial signal is most accessible on the largest scales, where the scale…
Constraining the Sub-Galactic Relationship Between Star Formation and the Hot Interstellar Medium in NGC 4254
Erik B. Monson, Bret D. Lehmer, Amirnezam Amiri +17
We investigate the relationship between star formation and X-ray emission from the hot interstellar medium (ISM) on kpc scales in NGC 4254 (M99) by combining spatially resolv…
Evolved Supergiants in PHANGS I: Red Supergiants in 19 Galaxies between 5-20 Mpc with HST and JWST
Sumit K. Sarbadhicary, David Thilker, Adam K. Leroy +17
Red supergiants (RSGs) are important for our understanding of supernova progenitors, stellar populations, stellar evolution, mass loss and dust production. Extragalactic surveys of…
PHANGS-JWST: the largest extragalactic molecular cloud catalog traced by polycyclic aromatic hydrocarbon emission
Z. Bazzi, D. Colombo, F. Bigiel +25
High-resolution JWST images of nearby spiral galaxies reveal polycyclic aromatic hydrocarbon (PAH) emission structures that trace molecular gas, including CO-dark regions. We ident…
Characterization of Two Cool Galaxy Outflow Candidates Using Mid-Infrared Emission from Polycyclic Aromatic Hydrocarbons
Jessica Sutter, Karin Sandstrom, Ryan Chown +22
We characterize two candidate cool galactic outflows in two relatively low mass, highly inclined Virgo cluster galaxies: NGC4424 and NGC4694. Previous analyses of observations usin…
Temperature based radial metallicity gradients in nearby galaxies
K. Kreckel, R. J. Rickards Vaught, O. V. Egorov +14
Gas-phase abundances provide insights into the baryon cycle, with radial gradients and 2D metallicity distributions tracking how metals build up and redistribute within galaxy disk…
The Hierarchical Dynamical State of Molecular Gas from 3 to 300 pc in NGC 253
Elias K. Oakes, Christopher M. Faesi, Erik Rosolowsky +25
Understanding how the dynamical state of the interstellar medium (ISM) changes across spatial scales can provide important insights into how the gas is organized and ultimately col…
Duration and properties of the embedded phase of star formation in 37 nearby galaxies from PHANGS-JWST
Lise Ramambason, Mélanie Chevance, Jaeyeon Kim +32
Light reprocessed by dust grains emitting in the infrared allows the study of the physics at play in dusty, embedded regions, where ultraviolet and optical wavelengths are attenuat…
Primary Beam Chromaticity in HIRAX: I. Characterization from Simulations and Power Spectrum Implications
Ajith Sampath, Devin Crichton, Kavilan Moodley +15
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is an upcoming radio interferometric telescope designed to constrain dark energy through the 21cm intensity mapping…
Constraining the growth rate on linear scales by combining SKAO and DESI surveys
Simthembile Dlamini, Sheean Jolicoeur, Roy Maartens
In the pursuit of understanding the large-scale structure of the Universe, the synergy between complementary cosmological surveys has proven to be a powerful tool. Using multiple t…
Constraining primordial non-Gaussianity by combining next-generation galaxy and 21 cm intensity mapping surveys
Sheean Jolicoeur, Roy Maartens, Simthembile Dlamini
Surveys of the matter distribution contain `fossil' information on possible non-Gaussianity that is generated in the primordial Universe. This primordial signal survives only on th…
