Tests of photometry: the case of the NGC 3370 ACS field
In Sung Jang
A critical analysis and comparison of different methods for obtaining point spread function (PSF) photometry are carried out. Deep ACS observations of NGC3370 were reduced using fo…
The Astrophysical Distance Scale: V. A 2% Distance to the Local Group Spiral M33 via the JAGB Method, Tip of the Red Giant Branch, and Leavitt Law
Abigail J. Lee, Laurie Rousseau-Nepton, Wendy L. Freedman +6
The J-region asymptotic giant branch (JAGB) method is a new standard candle that is based on the stable intrinsic J-band magnitude of color-selected carbon stars, and has a precisi…
The Hubble constant from two sibling Type Ia supernovae in the nearby galaxy NGC 4414: SN 1974G and SN 2021J
Eulalia Gallego-Cano, Luca Izzo, Carlos Dominguez-Tagle +4
Having two "sibling" Type Ia supernovae (SNe Ia) in the same galaxy offers additional advantages in reducing a variety of systematic errors involved in estimating the Hubble consta…
A Uniform Type Ia Supernova Distance Ladder with the Zwicky Transient Facility: Absolute Calibration Based on the Tip of the Red Giant Branch (TRGB) Method
Suhail Dhawan, Ariel Goobar, Joel Johansson +21
The current Cepheid-calibrated distance ladder measurement of is reported to be in tension with the values inferred from the cosmic microwave background (CMB), assuming stand…
