Discovery of Short-Term γ-Ray Pulsed Radiation Variations Following a Glitch in PSR J0205+6449
Wen-Tao Ye, Ming-Yu Ge, Shi-Jie Zheng +7
Rotation-powered pulsars exhibit stable emission characteristics most of the time. However, their radiative state can vary with the sudden changes of rotational state such as glitc…
Detection of a dark matter subhalo in the strongly lensed system PJ011646
Aristeidis Amvrosiadis, James W. Nightingale, Qiuhan He +12
We present a strong lensing analysis of the system PJ011646 using high-resolution (0.1 arcsec) Atacama Large Millimeter/submillimeter Array (ALMA) dust-continuum observations…
Measuring the Stellar-to-Halo Mass Relation at Solar masses, using forthcoming space-based imaging of galaxy-galaxy strong lenses
Kaihao Wang, Xiaoyue Cao, Ran Li +11
The stellar-to-halo mass relation (SHMR) is central to understanding the co-evolution of galaxies and their host dark matter haloes, yet it remains weakly constrained for dwarf gal…
Probing Dark Matter Substructures with Free-Form Modelling: A Case Study of the `Jackpot' Strong Lens
Xiaoyue Cao, Ran Li, James W. Nightingale +12
Characterising the population and internal structure of sub-galactic halos is critical for constraining the nature of dark matter. These halos can be detected near galaxies that ac…
The "Little Dark Dot": Evidence for Self-interacting Dark Matter in the Strong Lens SDSS J0946+1006?
Shubo Li, Ran Li, Kaihao Wang +13
Previous studies, based on precise modeling of a gravitationally lensing image, have identified what may be an extremely compact, dark perturber in the well-known lensing system SD…
Not so dark, not so dense: an alternative explanation for the lensing subhalo in SDSSJ0946+1006
Qiuhan He, Andrew Robertson, James W. Nightingale +12
Previous studies of the strong lens system SDSSJ0946+1006 have reported a dark matter subhalo with an unusually high central density, potentially challenging the standard cold dark…
