The PHANGS-HST-Halpha Survey: Warm Ionized Gas Physics at High Angular resolution in Nearby GalaxieS with the Hubble Space Telescope
Rupali Chandar, Ashley T. Barnes, David A. Thilker +36
The PHANGS project is assembling a comprehensive, multi-wavelength dataset of nearby (~5-20 Mpc), massive star-forming galaxies to enable multi-phase, multi-scale investigations in…
Excitation mechanisms of C II optical permitted lines in ionized nebulae
E. Reyes-Rodríguez, J. E. Méndez-Delgado, J. García-Rojas +4
Context. Carbon is the fourth most abundant element in the universe and its distribution is critical to understanding stellar evolution and nucleosynthesis. In optical studies of i…
A physically motivated `charge-exchange method' for measuring electron temperatures within HII regions
K. Kreckel, O. Egorov, F. Belfiore +9
Aims: Temperature uncertainties plague our understanding of abundance variations within the ISM. Using the PHANGS-MUSE large program, we develop and apply a new technique to model…
H Morphologies of Star Clusters in 16 LEGUS Galaxies: Constraints on HII region evolution timescales
Stephen Hannon, Janice C. Lee, Bradley C. Whitmore +14
The analysis of star cluster ages in tandem with the morphology of their HII regions can provide insight into the processes that clear a cluster's natal gas, as well as the accurac…
CHILES VI: HI and H Observations for z < 0.1 Galaxies; Probing HI Spin Alignment with Filaments in the Cosmic Web
J. Blue Bird, J. Davis, N. Luber +15
We present neutral hydrogen (HI) and ionized hydrogen (H) observations of ten galaxies out to a redshift of 0.1. The HI observations are from the first epoch (178 hours) of the…
A revised planetary nebula luminosity function distance to NGC 628 using MUSE
K. Kreckel, B. Groves, F. Bigiel +5
Distance uncertainties plague our understanding of the physical scales relevant to the physics of star formation in extragalactic studies. The planetary nebulae luminosity function…
The Void Galaxy Survey: Photometry, structure and identity of void galaxies
B. Beygu, R. F. Peletier, J. M. van der Hulst +5
We analyze photometry from deep B-band images of 59 void galaxies in the Void Galaxy Survey (VGS), together with their near-infrared 3.6m and 4.5m Spitzer photometry. The VGS…
Comparing [CII], HI, and CO dynamics of nearby galaxies
W. J. G. de Blok, F. Walter, J. -D. T Smith +12
The HI and CO components of the interstellar medium (ISM) are usually used to derive the dynamical mass M_dyn of nearby galaxies. Both components become too faint to be used as a t…
Nearby Clumpy, Gas Rich, Star Forming Galaxies: Local Analogs of High Redshift Clumpy Galaxies
C. A. Garland, D. J. Pisano, M. -M. Mac Low +3
Luminous compact blue galaxies (LCBGs) have enhanced star formation rates and compact morphologies. We combine Sloan Digital Sky Survey data with HI data of 29 LCBGs at redshift z~…
The Survey of Lines in M31 (SLIM): Investigating the Origins of [CII] Emission
M. J. Kapala, K. Sandstrom, B. Groves +7
The [CII] 158 micron line is one of the strongest emission lines observed in star-forming galaxies, and has been empirically measured to correlate with the star formation rate (SFR…
The metallicity of void dwarf galaxies
K. Kreckel, K. Croxall, B. Groves +2
The current Lambda CDM cosmological model predicts that galaxy evolution proceeds more slowly in lower density environments, suggesting that voids are a prime location to search fo…
A far-IR view of the starburst driven superwind in NGC 2146
K. Kreckel, L. Armus, B. Groves +19
NGC 2146, a nearby luminous infrared galaxy (LIRG), presents evidence for outflows along the disk minor axis in all gas phases (ionized, neutral atomic and molecular). We present a…
Towards A Removal of Temperature Dependencies from Abundance Determinations
Kevin V. Croxall, J. D. Smith, B. R. Brandl +16
The metal content of a galaxy is a key property for distinguishing between viable galaxy evolutionary scenarios, and it strongly influences many of the physical processes in the in…
The CO-to-H2 Conversion Factor and Dust-to-Gas Ratio on Kiloparsec Scales in Nearby Galaxies
K. M. Sandstrom, A. K. Leroy, F. Walter +42
We present kiloparsec (kpc) spatial resolution maps of the CO-to-H2 conversion factor (alpha_co) and dust-to-gas ratio (DGR) in 26 nearby, star-forming galaxies. We have simultaneo…
