Optical spectroscopy of faint gigahertz peaked spectrum sources [PDF]
, 1999 We present spectroscopic observations of a sample of faint Gigahertz Peaked
Spectrum (GPS) radio sources drawn from the Westerbork Northern Sky Survey
(WENSS). Redshifts have been determined for 19 (40%) of the objects.A. G. de Bruyn, Baker, Baldwin, Baldwin, De Vries, Dressler, Fanti, Fanti, G. K. Miley, H. J. A. Röttgering, Hook, I. A. G.

, 2017 Quasars are galaxies hosting accreting supermassive black holes; due to their brightness, they are unique probes of the early universe. To date, only a few quasars have been reported at (C.

The Astrophysical JournalSome optically selected quasars exhibit Mg ii- associated absorption lines (AALs), and their origin remains unclear. In this paper, we compile a sample of 1769 quasars, with or without Mg ii AALs, of which 1689 are far-infrared (FIR) detected quasars and Zhe-Geng Chen, Rui-Jing Lu, Zhi-Fu Chen, Wen-Qiang Liang, Xing-Long Peng, Jing Li, Wei-Rong Huang +6 moredoaj +1 more sourceA slitless spectroscopic survey for quasars near quasars

Advanced Science, EarlyView.EBV produces abundant level of lncBARTs, which are essential for maintaining viral genome replication in EBV‐associated cancers. LncBARTs interact with a complex comprising BRD4, CTCF and viral protein EBNA1 at EBV oriP region. This interaction tethers oriP to host chromosomes, facilitating EBV episome replication.Jiayan Liu, Dittman Lai‐Shun Chung, Larry Ka‐Yue Chow, Shuo Han, Wenkai Yi, Conor J.
