IllustrisTNG in the HSC-SSP: image data release and the major role of mini mergers as drivers of asymmetry and star formation
Connor Bottrell, Hassen M. Yesuf, Gergö Popping +13
At fixed galaxy stellar mass, there is a clear observational connection between structural asymmetry and offset from the star forming main sequence, SFMS. Herein, we use the TNG…
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…
Dynamical hotness, star formation quenching and growth of supermassive black holes
Hui Hong, Huiyuan Wang, H. J. Mo +8
A stellar system is dynamically hot when its kinetic energy is dominated by random motion represented by the velocity dispersion . We use MaNGA data to obtain in…
The cosmic web of X-ray active galactic nuclei seen through the eROSITA Final Equatorial Depth Survey (eFEDS)
Johan Comparat, Wentao Luo, Andrea Merloni +17
Which galaxies in the general population turn into active galactic nuclei (AGNs) is a keystone of galaxy formation and evolution. Thanks to SRG/eROSITA's contiguous 140 square degr…
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…
Massive Star-Forming Galaxies Have Converted Most of Their Halo Gas into Stars
Ziwen Zhang, Huiyuan Wang, Wentao Luo +5
In the local Universe, the efficiency for converting baryonic gas into stars is very low. In dark matter halos where galaxies form and evolve, the average efficiency varies with ga…
Hosts and triggers of AGNs in the Local Universe
Ziwen Zhang, Huiyuan Wang, Wentao Luo +11
Based on the spectroscopic and shear catalogs for SDSS galaxies in the local Universe, we compare optically-selected active galactic nuclei (AGNs) with control star-forming and qui…
A comparative study of satellite galaxies in Milky Way-like galaxies from HSC, DECaLS and SDSS
Wenting Wang, Masahiro Takada, Xiangchong Li +10
We conduct a comprehensive and statistical study of the luminosity functions (LFs) for satellite galaxies, by counting photometric galaxies from HSC, DECaLS and SDSS around isolate…
Dual supermassive black holes at close separation revealed by the Hyper Suprime-Cam Subaru Strategic Program
John D. Silverman, Shenli Tang, Khee-Gan Lee +30
The unique combination of superb spatial resolution, wide-area coverage, and deep depth of the optical imaging from the Hyper Suprime-Cam (HSC) Subaru Strategic Program is utilized…
Emergent gravity fails to explain color-dependent galaxy-galaxy lensing signals from SDSS Dr7
Wentao Luo, Jiajun Zhang, Vitali Halenka +6
We test the Emergent Gravity(EG) theory using the galaxy-galaxy lensing technique based on SDSS DR7 data. In the EG scenario, we do not expect color dependence of the galaxy sample…
The stellar halo of isolated central galaxies in the Hyper Suprime-Cam imaging survey
Wenting Wang, Jiaxin Han, Alessandro Sonnenfeld +14
We study the faint stellar halo of isolated central galaxies, by stacking galaxy images in the HSC survey and accounting for the residual sky background sampled with random points.…
ELUCID V. Lighting dark matter halos with galaxies
Xiaohu Yang, Youcai Zhang, Huiyuan Wang +16
In a recent study, using the distribution of galaxies in the north galactic pole of SDSS DR7 region enclosed in a 500$\mpch$ box, we carried out our ELUCID simulation (Wang et al.…
Revealing the cosmic web dependent halo bias
Xiaohu Yang, Youcai Zhang, Tianhuan Lu +7
Halo bias is the one of the key ingredients of the halo models. It was shown at a given redshift to be only dependent, to the first order, on the halo mass. In this study, four typ…
An empirical model to form and evolve galaxies in dark matter halos
Shijie Li, Youcai Zhang, Xiaohu Yang +8
Based on the star formation histories (SFH) of galaxies in halos of different masses, we develop an empirical model to grow galaxies in dark mattet halos. This model has very few i…
Connections between galaxy mergers and Starburst: evidence from local Universe
Wentao Luo, Xiaohu Yang, Youcai Zhang
Major mergers and interactions between gas-rich galaxies with comparable masses are thought to be the main triggers of starburst. In this work, we study, for a large stellar mass r…
