Reconnaissance with JWST of the J-region Asymptotic Giant Branch in Distance Ladder Galaxies: From Irregular Luminosity Functions to Approximation of the Hubble Constant
Siyang Li, Adam G. Riess, Stefano Casertano +5
We study stars in the J-regions of the asymptotic giant branch (JAGB) of near-infrared color magnitude diagrams in the maser host NGC 4258 and 4 hosts of 6 Type Ia supernovae (SN I…
JWST Observations Reject Unrecognized Crowding of Cepheid Photometry as an Explanation for the Hubble Tension at 8 sigma Confidence
Adam G. Riess, Gagandeep S. Anand, Wenlong Yuan +7
We present high-definition observations with the James Webb Space Telescope of >1000 Cepheids in a geometric anchor of the distance ladder, NGC4258, and in 5 hosts of 8 SNe~Ia, a f…
Tip of the Red Giant Branch Distances with JWST: An Absolute Calibration in NGC 4258 and First Applications to Type Ia Supernova Hosts
Gagandeep S. Anand, Adam G. Riess, Wenlong Yuan +12
The tip of the red giant branch (TRGB) allows for the measurement of precise and accurate distances to nearby galaxies, based on the brightest ascent of low-mass red giant branch s…
Crowded No More: The Accuracy of the Hubble Constant Tested with High Resolution Observations of Cepheids by JWST
Adam G. Riess, Gagandeep S. Anand, Wenlong Yuan +7
High-resolution JWST observations can test confusion-limited HST observations for a photometric bias that could affect extragalactic Cepheids and the determination of the Hubble co…
Is there a dwarf galaxy satellite-of-satellite problem in CDM?
Oliver Müller, Nick Heesters, Helmut Jerjen +2
Dark matter clusters on all scales, therefore it is expected that even substructure should host its own substructure. Using the Extragalactic Distance Database, we searched for dwa…
A nearby isolated dwarf: star formation and structure of ESO 006-001
Lidia N. Makarova, R. Brent Tully, Gagandeep S. Anand +4
Observations with the Hubble Space Telescope unexpectedly revealed that the dwarf galaxy ESO 006-001 is a near neighbor to the Local Group at a distance of 2.70 +- 0.11 Mpc. The st…
