Kavli Affiliate: Aaron Roodman | First 5 Authors: Ji Won Park, Simon Birrer, Madison Ueland, Miles Cranmer, Adriano Agnello | Summary: We present a Bayesian graph neural network (BGNN) that can estimate the weak lensing convergence ($kappa$) from photometric measurements of galaxies along a given line of sight. The method is of particular interest in […]
Kavli Affiliate: Jing Wang | First 5 Authors: Phanuel Mariano, Jing Wang, , , | Summary: Assuming the heat kernel on a doubling Dirichlet metric measure space has a generalized sub-Gaussian bound, we prove an asymptotically sharp spectral upper bound on the survival probability of the associated diffusion process. As a consequence, we can show […]
Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Jason Poh, Ashwin Samudre, Aleksandra Ćiprijanović, Brian Nord, Gourav Khullar | Summary: Current ground-based cosmological surveys, such as the Dark Energy Survey (DES), are predicted to discover thousands of galaxy-scale strong lenses, while future surveys, such as the Vera Rubin Observatory Legacy Survey of Space and […]

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Marta Monelli, Eiichiro Komatsu, Alexandre E. Adler, Matteo Billi, Paolo Campeti | Summary: Polarization of the cosmic microwave background (CMB) can probe new parity-violating physics such as cosmic birefringence (CB), which requires exquisite control over instrumental systematics. The non-idealities of the half-wave plate (HWP) represent a source […]
Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Michelle Kunimoto, Evan Tey, Willie Fong, Katharine Hesse, Avi Shporer | Summary: We present High-Level Science Products (HLSPs) containing light curves from MIT’s Quick-Look Pipeline (QLP) from the second year of TESS’ first Extended Mission (Sectors 40 – 55; 2021 July – 2022 September). In total, 12.2 […]
Kavli Affiliate: Sarah Church | First 5 Authors: Gaspar Galaz, David T. Frayer, Matias Blaña, J. Christopher Howk, Thomas Puzia | Summary: We report on results from GBT/ARGUS $^{12}$CO(1-0) observations for the giant low surface brightness galaxy Malin 1, which allow us to determine an upper limit for its CO mass, and hence its molecular […]
Kavli Affiliate: Lee McCuller | First 5 Authors: Lee McCuller, , , , | Summary: The Michelson interferometer is a cornerstone of experimental physics. Its applications range from providing first impressions of wave interference in educational settings to probing spacetime at minuscule precision scales. Interferometer precision provides a unique view of the fundamental medium of […]
Kavli Affiliate: Kejia Lee | First 5 Authors: Mingyu Ge, Yuan-Pei Yang, Fangjun Lu, Shiqi Zhou, Long Ji | Summary: Fast radio bursts (FRBs) are short pulses observed in radio frequencies usually originating from cosmological distances. The discovery of FRB 200428 and its X-ray counterpart from the Galactic magnetar SGR J1935+2154 suggests that at least […]
