A Comprehensive Measurement of the Local Value of the Hubble Constant with 1 km/s/Mpc Uncertainty from the Hubble Space Telescope and the SH0ES Team
Adam G. Riess, Wenlong Yuan, Lucas M. Macri +15
We report observations from HST of Cepheids in the hosts of 42 SNe Ia used to calibrate the Hubble constant (H0). These include all suitable SNe Ia in the last 40 years at z<0.01,…
KK 242, a faint companion to the isolated Scd galaxy NGC 6503
Igor D. Karachentsev, John M. Cannon, Jackson Fuson +4
Using Hubble Space Telescope imaging of the resolved stellar population of KK~242 = NGC6503-d1 = PGC~4689184, we measure the distance to the galaxy to be Mpc and find…
The Whisper of a Whimper of a Bang: 2400 Days of the Type Ia SN 2011fe Reveals the Decay of Fe
M. A. Tucker, B. J. Shappee, C. S. Kochanek +4
We analyze new multi-filter Hubble Space Telescope (HST) photometry of the normal Type Ia supernova (SN Ia) 2011fe out to days after maximum light, the latest observ…
The PHANGS-MUSE survey -- Probing the chemo-dynamical evolution of disc galaxies
Eric Emsellem, Eva Schinnerer, Francesco Santoro +45
We present the PHANGS-MUSE survey, a programme using the MUSE IFS at the ESO VLT to map 19 massive nearby (D < 20 Mpc) star-forming disc galaxi…
Measuring an off-Center Detonation through Infrared Line Profiles: The peculiar Type Ia Supernova SN~2020qxp/ASASSN-20jq
P. Hoeflich, C. Ashall, S. Bose +17
We present and analyze a near infrared(NIR) spectrum of the under-luminous Type Ia supernova SN~2020qxp/ASASSN-20jq obtained with NIRES at the Keck Observatory 191 days after B-ban…
Comparing Tip of the Red Giant Branch Distance Scales: An Independent Reduction of the Carnegie-Chicago Hubble Program and the Value of the Hubble Constant
Gagandeep S. Anand, R. Brent Tully, Luca Rizzi +2
The tip of the red giant branch has been used to measure distances to 500 nearby galaxies with the Hubble Space Telescope (HST) which are available in the Color-Magnitude Diagrams…
The Extragalactic Distance Database: The Color-Magnitude Diagrams and Tip of the Red Giant Branch Distances Catalog
Gagandeep S. Anand, Luca Rizzi, R. Brent Tully +7
The Extragalactic Distance Database (EDD) was created as a repository for high quality, redshift-independent distances. A key component of EDD is the Color Magnitude Diagrams/Tip o…
PHANGS-ALMA: Arcsecond CO(2-1) Imaging of Nearby Star-Forming Galaxies
Adam K. Leroy, Eva Schinnerer, Annie Hughes +69
We present PHANGS-ALMA, the first survey to map CO J=2-1 line emission at ~1" ~ 100pc spatial resolution from a representative sample of 90 nearby (d<~20 Mpc) galaxies that lie on…
PHANGS-ALMA Data Processing and Pipeline
Adam K. Leroy, Annie Hughes, Daizhong Liu +65
We describe the processing of the PHANGS-ALMA survey and present the PHANGS-ALMA pipeline, a public software package that processes calibrated interferometric and total power data…
Late-Onset Circumstellar Medium Interactions are Rare: An Unbiased GALEX View of Type Ia Supernovae
Liam O. Dubay, Michael A. Tucker, Aaron Do +2
Using ultraviolet (UV) light curves we constrain the circumstellar environments of 1080 Type Ia supernovae (SNe Ia) within from archival Galaxy Evolution Explorer (GALEX) o…
Distance and mass of the NGC 253 galaxy group
Igor D. Karachentsev, R. Brent Tully, Gagandeep S. Anand +2
Two dwarf galaxies: WOC2017-07 and PGC 704814 located in the vicinity of the nearby luminous spiral galaxy NGC 253 were observed with the Advanced Camera for Surveys on the Hubble…
The PHANGS-HST Survey: Physics at High Angular resolution in Nearby GalaxieS with the Hubble Space Telescope
Janice C. Lee, Bradley C. Whitmore, David A. Thilker +51
The PHANGS program is building the first dataset to enable the multi-phase, multi-scale study of star formation across the nearby spiral galaxy population. This effort is enabled b…
