Autor: Dawei Li, Taotao Fang, Chong Ge, Teng Liu, Lin He, Zhiyuan Li, Fabrizio Nicastro, Xiaohu Yang, Xiaoxia Zhang, Yun-Liang Zheng

Publikováno v: The Astrophysical Journal Letters, Vol 977, Iss 2, p L40 (2024)

Over the last several decades, extensive research has been conducted on the baryon cycles within cosmic structures, encompassing a broad mass range from dwarf galaxies to galaxy clusters. However, a notable gap in understanding the cosmic baryon cycl

Cosmic Reionization in the JWST Era: Back to AGNs?

Autor: Piero Madau, Emanuele Giallongo, Andrea Grazian, Francesco Haardt

Publikováno v: The Astrophysical Journal, Vol 971, Iss 1, p 75 (2024)

Deep surveys with the James Webb Space Telescope (JWST) have revealed an emergent population of moderate-luminosity, broad-line active galactic nuclei (AGNs) at 4 ≲ z ≲ 13 powered by accretion onto early massive black holes. The high number densi

Detection of Thermal Sunyaev–Zel’dovich Effect in the Circumgalactic Medium of Low-mass Galaxies—A Surprising Pattern in Self-similarity and Baryon Sufficiency

Autor: Sanskriti Das, Yi-Kuan Chiang, Smita Mathur

Publikováno v: The Astrophysical Journal, Vol 951, Iss 2, p 125 (2023)

We report on the measurement of the thermal Sunyaev–Zel’dovich (tSZ) effect in the circumgalactic medium (CGM) of 641,923 galaxies with M _⋆ = 10 ^9.8–11.3 M _⊙ at z < 0.5, pushing the exploration of the tSZ effect to lower-mass galaxies co
