Constraining the quasar radio-loud fraction at with deep radio observations
Yuanqi Liu, Ran Wang, Emmanuel Momjian +8
We carry out a series of deep Karl G. Jansky Very Large Array (VLA) S-band observations of a sample of 21 quasars at . The new observations expand the searches of radio con…
Close-up view of a luminous star-forming galaxy at z=2.95
S. Berta, A. J. Young, P. Cox +35
(Abridged) Exploiting the sensitivity and broad band width of NOEMA, we have studied the molecular gas and dust in the galaxy HerBS-89a, at z=2.95. High angular resolution images r…
SCUBA2 High Redshift Bright Quasar Survey: Far-infrared Properties and Weak-line Features
Qiong Li, Ran Wang, Xiaohui Fan +13
We present a submillimetre continuum survey ('SCUBA2 High rEdshift bRight quasaR surveY', hereafter SHERRY) of 54 high redshift quasars at with quasar bolometric lumino…
Ionized and atomic interstellar medium in the z = 6.003 quasar SDSS J2310+1855
Jianan Li, Ran Wang, Pierre Cox +13
Observing the interstellar medium (ISM) in quasars host galaxies is essential for understanding the co-evolution between the supermassive black holes and their hosts.…
86 GHz SiO masers in Galactic Centre OH/IR stars
M. Messineo, L. O. Sjouwerman, H. J. Habing +1
We present results on a search for 86.243 GHz SiO (J = 2 -- 1, v = 1) maser emission toward 67 OH/IR stars located near the Galactic Centre. We detected 32 spectral peaks, of which…
Etching glass in the early Universe: Luminous HF and water emission in a QSO-SMG pair at z=4.7
M. D. Lehnert, C. Yang, B. H. C. Emonts +4
(abridged) We present ALMA observations of hydrogen fluoride, HF J=1-0, H20 (220-211), and the 1.2 THz rest-frame continuum emission from the z=4.7 system BR1202-0725. BR1202-0725…
