A sound horizon independent measurement of from BOSS, DESI and DES Y3
Zhiyu Lu, Théo Simon, Vivian Poulin +1
We present a sound horizon independent measurement of the Hubble parameter using a multiprobe large-scale structure analysis. Removing the dependency on the sound horizon with a re…
Atomic Quantum Sensors for High-Frequency Gravitational Wave Searches
Yi-fu Cai, Luca Visinelli, Sheng-Feng Yan
High-frequency gravitational waves (GWs), spanning frequencies from the microwave to the optical band, remain experimentally unexplored despite strong motivation from early-Univers…
Isocurvature Induced Gravitational Waves at Pulsar Timing Arrays
Yi-Fu Cai, Peizhi Du, Jiahang Zhong
Gravitational waves (GWs) are powerful probes of new physics in the early Universe. In particular, GWs induced by primordial isocurvature perturbations encode information of novel…
CFHT MegaCam Two Deep Fields Imaging Survey (2DFIS) I: Overview
Binyang Liu, Wentao Luo, Martin Kilbinger +14
We present the Two Deep Fields Imaging Survey (2DFIS), a wide-field imaging program conducted with the Canada-France-Hawaii Telescope (CFHT) targeting two astrophysically distinct…
(Lovelock) inflation: explaining the ACT data and equivalence to Higgs-Gauss-Bonnet inflation
Andrea Addazi, Yermek Aldabergenov, Daulet Berkimbayev +1
We revisit the Starobinsky model of inflation in light of recent data from the Atacama Cosmology Telescope (ACT), which indicates a potential preference for a slightly larger scala…
Static Microlensing: Concept, Method and Candidates
Qi Guo, Leyao Wei, Wentao Luo +6
We propose a novel microlensing event search method that differs from either the traditional time domain method, astrometric microlensing, or the parallax microlensing method. Our…
