Star Cluster Populations in 38 Spiral Galaxies: Evidence for Near-Universal Mass and Age Distributions from PHANGS
Rupali Chandar, Matthew R. Floyd, David A. Thilker +23
We present the largest study to date of star cluster mass and age distributions in nearby galaxies. The analysis is based on a uniformly selected catalog of over 15,000 (36,000) hu…
Mid-Infrared Colors Vary with Galactic Environment: Contrasting Star-Forming Disks, Young Centers, and Quiescent Star-Formation Deserts
Debosmita Pathak, Karin M. Sandstrom, Adam K. Leroy +27
We present pc-resolution JWST/MIRI and NIRCam measurements of mid-infrared (mid-IR) color variations in the diffuse interstellar medium (ISM) of 71 nearby star-forming…
Determining star formation histories and age-metallicity relations with convolutional neural networks
Enrique Galceran, Patricia Sánchez-Blázquez, Artemi Camps-Fariña +8
We aim to develop a state-of-the-art tool to infer detailed star formation histories (SFHs) and age-metallicity relations from realistic observational data, while mitigating classi…
HI Observations of Giant Low Surface Brightness Galaxies
Philip Lah, Nikhil Arora, Ivan Yu. Katko +5
Giant low surface brightness galaxies (gLSBs) are galaxies with extremely extended, faint, optical disks over 50 kpc in radius and have high total masses which can reach 10^12 sola…
The Nuclear Star Cluster of M 74: a fossil record of the very early stages of a star-forming galaxy
Francesca Pinna, Nils Hoyer, Jairo Méndez Abreu +13
Nuclear star clusters (NSC) are dense and compact stellar systems, of sizes of few parsecs, located at galactic centers. Their properties and formation mechanisms seem to be tightl…
Ashes of Creation: JWST Uncovers Silicate Dust in Massive Star Clusters
Daniel Maschmann, Bradley C. Whitmore, David A. Thilker +35
Dust production is a fundamental aspect of the baryonic cycle of star formation. It is known that dust is injected into the interstellar medium during early star formation by super…
Polycyclic aromatic hydrocarbons destruction in star-forming regions across 42 nearby galaxies
Oleg V. Egorov, Adam K. Leroy, Karin Sandstrom +30
Polycyclic aromatic hydrocarbons (PAHs) are widespread in the interstellar medium (ISM) of Solar metallicity galaxies, where they play a critical role in ISM heating, cooling, and…
MUSE Study of Two Giant Low-surface-brightness Galaxies with Compact Satellites
Anna S. Saburova, Damir Gasymov, Ivan S. Gerasimov +7
Giant low-surface-brightness disk galaxies (gLSBGs) are rare objects with disk radii up-to 160 kpc and dynamical masses of an order of up to 10 . Their very exist…
The Hidden Life of Stars: Embedded Beginnings to AGB Endings in the PHANGS-JWST Sample. I. Catalog of Mid-IR Sources
Hamid Hassani, Erik Rosolowsky, Adam K. Leroy +28
We present a multiwavelength catalog of mid-infrared-selected compact sources in 19 nearby galaxies, combining JWST NIRCam/MIRI, HST UV-optical broadband, H narrow-band, and ALM…
Chemical abundances and small-scale gas kinematics in the local star-forming galaxy NGC 2366
Anastasiya D. Yarovova, Ivan S. Gerasimov, Oleg V. Egorov +3
We present a detailed spectroscopic study of ionised gas in the nearby (~3.3Mpc) dwarf galaxy NGC 2366, a local analogue of Green Pea galaxies, based on observations with the SCORP…
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…
A closer look at the extended edge-on low-surface brightness galaxies
Anna S. Saburova, Damir Gasymov, Evgenii V. Rubtsov +13
To understand the origin of extended disks of low-surface brightness (LSB) galaxies, we studied in detail 4 such systems with large disks seen edge-on. Two of them are edge-on gian…
Nature of the diffuse emission sources in the H I supershell in the galaxy IC 1613
Anastasiya D. Yarovova, Alexei V. Moiseev, Ivan S. Gerasimov +6
We present a study of the nearby low-metallicity dwarf galaxy IC 1613, focusing on the search for massive stars and related feedback processes, as well as for faint supernova remna…
Stellar feedback impact on the ionized gas kinematics in the dwarf galaxy Sextans B
Ivan S. Gerasimov, Oleg . V. Egorov, Alexei V. Moiseev +3
We investigated the ionised and atomic gas kinematics and excitation state in the central region of ongoing star formation of the nearby low-metallicity dwarf galaxy Sextans B. The…
Stellar feedback impact on the ionized gas kinematics in the dwarf galaxy Sextans A
Ivan S. Gerasimov, Oleg V. Egorov, Tatiana A. Lozinskaya +2
Feedback from massive stars shapes the ISM and affects the evolution of galaxies, but its mechanisms acting at the small scales ( pc) are still not well constrained observ…
