Implications of Inelastic Dark Matter for Primordial Dark-Star Evolution: Kinematic Thresholds and Nonthermal Capture

Qinxun Li, Shengyi Liu

The recent 248-keV nuclear recoil candidate reported by LUX-ZEPLIN has renewed interest in endothermic inelastic dark matter, motivating us to examine its capture in primordial dar…

Kinematic Lensing Ratio: Reviving Weak Lensing Cosmography as a Geometric Dark Energy Probe

Qinxun Li

We introduce the kinematic lensing ratio (KiLeR), a geometric dark-energy probe from weak lensing. Combining shear ratios with intrinsic galaxy shapes inferred from kinematics, KiL…

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…

Radio AGN feedback sustains quiescence only in a minority of massive galaxies

Huiling Liu, Yan Lu, Hui Hong +11

Radio active galactic nuclei (AGNs) eject a huge amount of energy into the surrounding medium and are thought to potentially prevent gas cooling and maintain the quiescence of mass…

UNIONS: The Ultraviolet Near-Infrared Optical Northern Survey

Stephen Gwyn, Alan W. McConnachie, Jean-Charles Cuillandre +86

The Ultraviolet Near-Infrared Optical Northern Survey (UNIONS) is a "collaboration of collaborations" that is using the Canada-France-Hawai'i Telescope, the Pan-STARRS telescopes,…

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…

Point-Spread Function errors for weak lensing - density cross-correlations. Application to UNIONS

Ziwen Zhang, Martin Kilbinger, Fabian Hervas Peters +8

Aims:Calibrating the point spread function (PSF) is a fundamental part of weak gravitational lensing analyses. Even with corrected galaxy images, imperfect calibrations can introdu…

Testing Cotton gravity as dark matter substitute with weak lensing

Geyu Mo, Qingqing Wang, Xin Ren +3

Harada proposed a modified theory of gravity called Cotton gravity, and argued that it successfully explains the rotation curves of galaxies without the need of dark matter. I…

Black-Hole-to-Halo Mass Relation From UNIONS Weak Lensing

Qinxun Li, Martin Kilbinger, Wentao Luo +17

This letter presents, for the first time, direct constraints on the black-hole-to-halo-mass relation using weak gravitational lensing measurements. We construct type I and type II…

Halo mass-observable proxy scaling relations and their dependencies on galaxy and group properties

Ziwen Zhang, Huiyuan Wang, Wentao Luo +5

Based on the DECaLS shear catalog, we study the scaling relations between halo mass() and various proxies for SDSS central galaxies, including stellar mass(), stell…

The density profile of Milky Way dark matter halo constrained from the OGLE microlensing sky map

Shu-Rui Lin, Wentao Luo, Yi-Fu Cai +6

We report the detection of a 282 pc-sized core in the center of Milky Way dark matter halo at confidence level by using the micro-lensing event rate sky map d…

Dark matter halos of luminous AGNs from galaxy-galaxy lensing with the HSC Subaru Strategic Program

Wentao Luo, John D. Silverman, Surhud More +12

We assess the dark matter halo masses of luminous AGNs over the redshift range 0.2 to 1.2 using galaxy-galaxy lensing based on imaging data from the Hyper Suprime-Cam Subaru Strate…
