Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Rodolfo Capdevilla, David Curtin, Yonatan Kahn, Gordan Krnjaic, | Summary: We comprehensively study all viable new-physics scenarios that resolve the muon $(g-2)_mu$ anomaly with only Standard Model singlet particles coupled to muons. Since such models are only viable in the MeV — TeV mass range and require […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman, Abigail Lee, , | Summary: We present an absolute calibration of the J-region Asymptotic Giant Branch (JAGB) method using published photometry of resolved stars in 20 nearby galaxies observed with HST using the WFC3-IR camera and the F110W (Broad J-Band) […]
Kavli Affiliate: Katrin Heitmann | First 5 Authors: Xiaofeng Dong, Nesar Ramachandra, Salman Habib, Katrin Heitmann, Michael Buehlmann | Summary: The potential of deep learning based image-to-image translations has recently drawn a lot of attention; one intriguing possibility is that of generating cosmological predictions with a drastic reduction in computational cost. Such an effort requires […]
Kavli Affiliate: Wayne Hu | First 5 Authors: David Zegeye, Keisuke Inomata, Wayne Hu, , | Summary: Single field inflationary models that seek to greatly enhance small scale power in order to form primordial black holes predict both a squeezed bispectrum that is enhanced by this small scale power and a potentially detectable enhancement of […]
Kavli Affiliate: Angela V. Olinto | First 5 Authors: Claire Guépin, Roberto Aloisio, Luis A. Anchordoqui, Austin Cummings, John F. Krizmanic | Summary: The evidence for dark matter particles, $chi$, is compelling based on Galactic to cosmological scale observations. Thus far, the promising weakly interacting massive particle scenario have eluded detection, motivating alternative models of […]
Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Viraj Manwadkar, Andrey Kravtsov, , , | Summary: We use texttt{GRUMPY}, a simple regulator-type model for dwarf galaxy formation and evolution, to forward model dwarf galaxy satellite population of the Milky Way (MW) using the Caterpillar zoom-in simulation suite. We show that luminosity and distance distributions of […]
Kavli Affiliate: Richard Kessler | First 5 Authors: Brodie Popovic, Dillon Brout, Richard Kessler, Daniel Scolnic, | Summary: Recent studies have shown that the observed colour distributions of Type Ia SNe (SNIa) are well-described by a combination of distributions from dust and intrinsic colour. Here we present a new forward-modeling fitting method (Dust2Dust) to measure […]
Kavli Affiliate: Bradford Benson | First 5 Authors: Yun Wang, Lee Armus, Andrew Benson, Emanuele Daddi, Andreas Faisst | Summary: ISCEA (Infrared Satellite for Cosmic Evolution Astrophysics) is a small astrophysics mission whose Science Goal is to discover how galaxies evolved in the cosmic web of dark matter at cosmic noon. Its Science Objective is […]
Kavli Affiliate: Richard Kessler | First 5 Authors: Anthony Carr, Tamara M. Davis, Daniel Scolnic, Khaled Said, Dillon Brout | Summary: We examine the redshifts of a comprehensive set of published Type Ia supernovae, and provide a combined, improved catalog with updated redshifts. We improve on the original catalogs by using the most up-to-date heliocentric […]
Kavli Affiliate: Donald G. York | First 5 Authors: Varsha P. Kulkarni, David V. Bowen, Lorrie A. Straka, Donald G. York, Neeraj Gupta | Summary: We report {it HST} COS spectroscopy of 10 quasars with foreground star-forming galaxies at 0.02$<$$z$$<$ 0.14 within impact parameters of $sim$1-7 kpc. We detect damped/sub-damped Ly$alpha$ absorption in 100$%$ of […]
