POEMMA (Probe of Extreme Multi-Messenger Astrophysics) Roadmap Update

Kavli Affiliate: Angela V. Olinto | First 5 Authors: Angela V. Olinto, , , , | Summary: The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) was designed as a NASA Astrophysics probe-class mission to identify the sources of ultrahigh energy cosmic rays (UHECRs) and observe cosmic neutrinos from extremely energetic transient sources. POEMMA consists of two […]

Dissecting the Thermal SZ Power Spectrum by Halo Mass and Redshift in SPT-SZ Data and Simulations

Kavli Affiliate: Lindsey Bleem | First 5 Authors: Josemanuel Hernandez, Lindsey Bleem, Thomas Crawford, Nicholas Huang, Yuuki Omori | Summary: We explore the relationship between the thermal Sunyaev-Zel’dovich (tSZ) power spectrum amplitude and the halo mass and redshift of galaxy clusters in South Pole Telescope (SPT) data, in comparison with three $N$-body simulations combined with […]

Systematics in the Cepheid and TRGB Distance Scales: Metallicity Sensitivity of the Wesenheit Leavitt Law

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 […]

Taking the Milky Way for a spin: disc formation in the ARTEMIS simulations

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 […]

Amalgame: Cosmological Constraints from the First Combined Photometric Supernova Sample

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 […]

Progress in Direct Measurements of the Hubble Constant

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) […]
