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…

Testing the isothermal Jeans model for self-interacting dark matter halos in the collapse phase

Shubo Li, Moritz S. Fischer, Zixiang Jia +3

We benchmark the semi-analytical isothermal Jeans model against a high-resolution isolated N-body simulation that follows a self-interacting dark matter (SIDM) halo into deep core…

An Enhanced Isothermal Jeans Approach to Constraining Dark Matter Self-Interactions from Galactic Kinematics

Zixiang Jia, Fangzhou Jiang, Shubo Li +3

We present an improved semi-analytical model to predict density profiles of self-interacting dark matter (SIDM) halos and apply it to constrain the self-scattering cross section us…

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…

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…

MaNGA DynPop -- VI. Matter density slopes from dynamical models of 6000 galaxies versus cosmological simulations: the interplay between baryonic and dark matter

Shubo Li, Ran Li, Kai Zhu +5

We try to understand the trends in the mass density slopes as a function of galaxy properties. We use the results from the best Jeans Anisotropic Modelling (JAM) of the integral-fi…
