Iron-corrected Single-epoch Black Hole Masses of DESI Quasars at low redshift

Zhiwei Pan, Linhua Jiang, Wei-Jian Guo +31

We present a study on the possible overestimation of single-epoch supermassive black hole (SMBH) masses in previous works, based on more than 55,000 type 1 quasars at $0.25 < z < 0…

The first identification of Lyman Changing-look Quasars at high-redshift in DESI

Wei-Jian Guo, Zhiwei Pan, Małgorzata Siudek +38

We present two cases of Ly changing-look (CL) quasars (J1306 and J1512) along with two additional candidates (J1511 and J1602), all discovered serendipitously at through…
