Variations in the 3.3 m Polycyclic Aromatic Hydrocarbon Feature Across Nearby Galaxies Driven by Metallicity and Radiation Field Spectrum

Hannah B. Koziol, Karin Sandstrom, Dalya Baron +29

We use JWST NIRCam imaging to investigate the 3.3 m polycyclic aromatic hydrocarbon (PAH) feature in nearby galaxies. NIRCam observations of the 3.3 m feature are emerging as…

The Roasting Marshmallows Program with IGRINS on Gemini South V: Atmosphere of MASCARA-1b is Enriched in Refractory Elements

Krishna Kanumalla, Michael R. Line, Martina Chiarella +75

Ultra-hot Jupiters (UHJs; K) enable simultaneous detection of volatile (ice-forming) and refractory (rock-forming) species in planetary atmospheres, provi…

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…

PAH Marks the Spot: Digging for Buried Clusters in Nearby Star-forming Galaxies

Gabrielle B. Graham, Daniel A. Dale, Chase L. Smith +39

The joint capabilities of the Hubble Space Telescope (HST) and JWST allow for an unparalleled look at the early lives of star clusters at near- and mid-infrared wavelengths. We pre…

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…

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…

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…

An Early Look at the Performance of IGRINS-2 at Gemini-North with Application to the ultrahot Jupiter, WASP-33 b

Yeon-Ho Choi, Ueejeong Jeong, Jae-Joon Lee +56

Ground-based high-resolution spectroscopy enables precise molecular detections and velocity-resolved atmospheric dynamics, offering a distinct advantage over low-resolution methods…

Multiple Populations of the Large Magellanic Cloud Globular Cluster NGC 2257: No Major Environmental Effect on the Formation of Multiple Populations of the Old Globular Clusters in Large Magellanic Cloud

Jae-Woo Lee, Tae-Hyeong Kim, Hak-Sub Kim +3

How the environment of the host galaxy affects the formation of multiple populations (MPs) in globular clusters (GCs) is one of the outstanding questions in the near-field cosmolog…

Tracing the earliest stages of star and cluster formation in 19 nearby galaxies with PHANGS-JWST and HST: compact 3.3 m PAH emitters and their relation to the optical census of star clusters

M. Jimena Rodríguez, Janice C. Lee, Remy Indebetouw +25

The earliest stages of star and cluster formation are hidden within dense cocoons of gas and dust, limiting their detection at optical wavelengths. With the unprecedented infrared…

PHANGS-HST catalogs for 100,000 star clusters and compact associations in 38 galaxies: I. Observed properties

Daniel Maschmann, Janice C. Lee, David A. Thilker +24

We present the largest catalog to-date of star clusters and compact associations in nearby galaxies. We have performed a V-band-selected census of clusters across the 38 spiral gal…

The One-hundred-deg^2 DECam Imaging in Narrowbands (ODIN): Survey Design and Science Goals

Kyoung-Soo Lee, Eric Gawiser, Changbom Park +39

We describe the survey design and science goals for ODIN (One-hundred-deg^2 DECam Imaging in Narrowbands), a NOIRLab survey using the Dark Energy Camera (DECam) to obtain deep (AB~…

H Morphologies of Star Clusters: A LEGUS study of HII region evolution timescales and stochasticity in low mass clusters

Stephen Hannon, Janice C. Lee, B. C. Whitmore +25

The morphology of HII regions around young star clusters provides insight into the timescales and physical processes that clear a cluster's natal gas. We study ~700 young clusters…
