From Halos to Galaxies. VI. Improved halo mass estimation for SDSS groups and measurement of the halo mass function

Kavli Affiliate: Yingjie Peng | First 5 Authors: Dingyi Zhao, Yingjie Peng, Yipeng Jing, Xiaohu Yang, Luis C. Ho | Summary: In $Lambda$CDM cosmology, galaxies form and evolve in their host dark matter (DM) halos. Halo mass is crucial for understanding the halo-galaxy connection. The abundance matching (AM) technique has been widely used to derive […]

The MAGPI Survey: the evolution and drivers of gas turbulence in intermediate-redshift galaxies

Kavli Affiliate: Yingjie Peng | First 5 Authors: Yifan Mai, Scott M. Croom, Emily Wisnioski, Sam P. Vaughan, Mathew R. Varidel | Summary: We measure the ionised gas velocity dispersions of star-forming galaxies in the MAGPI survey ($zsim0.3$) and compare them with galaxies in the SAMI ($zsim0.05$) and KROSS ($zsim1$) surveys to investigate how the […]

Féeton dark matter above the $e^-e^+$ threshold

Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Tatsuya Hayashi, Shigeki Matsumoto, Yuki Watanabe, Tsutomu T. Yanagida, | Summary: The new gauge boson introduced in the minimal extension of the standard model (SM) by gauging the U(1)$_{rm B-L}$ symmetry plays the role of dark matter when the U(1)$_{rm B-L}$ gauge coupling is highly suppressed. This […]

Testing Gravity with Realistic Gravitational Waveforms in Pulsar Timing Arrays

Kavli Affiliate: Wayne Hu | First 5 Authors: Wayne Hu, Qiuyue Liang, Meng-Xiang Lin, Mark Trodden, | Summary: We consider the effects of relaxing the assumption that gravitational waves composing the stochastic gravitational wave background (SGWB) are uncorrelated between frequencies in analyses of the data from Pulsar Timing Arrays (PTAs). While individual monochromatic plane waves […]
