Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman, , , | Summary: Using an updated and significantly augmented sample of Cepheid and TRGB distances to 28 nearby spiral and irregular galaxies, covering a wide range of metallicities, we have searched for evidence of a correlation of the zero-point […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Adam M. Dillamore, Vasily Belokurov, Andrey Kravtsov, Andreea S. Font, | Summary: We investigate the formation (spin-up) of galactic discs in the ARTEMIS simulations of Milky Way-mass galaxies. In almost all galaxies discs spin up at higher [Fe/H] than the Milky Way (MW). Those that contain an […]

Kavli Affiliate: Richard Kessler | First 5 Authors: Brodie Popovic, Daniel Scolnic, Maria Vincenzi, Mark Sullivan, Dillon Brout | Summary: Future constraints of cosmological parameters from Type Ia supernovae (SNe Ia) will depend on the use of photometric samples, those samples without spectroscopic measurements of the SNe Ia. There is a growing number of analyses […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Wendy L. Freedman, Barry F. Madore, , , | Summary: One of the most exciting and pressing issues in cosmology today is the discrepancy between some measurements of the local Hubble constant and other values of the expansion rate inferred from the cosmic microwave background (CMB) […]

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Christian Capanelli, Leah Jenks, Edward W. Kolb, Evan McDonough, | Summary: The Kalb-Ramond field is an antisymmetric, rank-two tensor field which most notably appears in the context of string theory, but has largely been unexplored in the context of cosmology. In this work, motivated by the […]

Kavli Affiliate: Chihway Chang | First 5 Authors: Meng-Xiang Lin, Bhuvnesh Jain, Marco Raveri, Eric J. Baxter, Chihway Chang | Summary: The $S_8$ tension between low-redshift galaxy surveys and the primary CMB signals a possible breakdown of the $Lambda$CDM model. Recently differing results have been obtained using low-redshift galaxy surveys and the higher redshifts probed […]
