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: , , , , | 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 gas mass and molecular gas mass surface density […]
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 […]
