The High-Redshift Clusters Occupied by Bent Radio AGN (COBRA) Survey: Investigating the Role of Environment on Bent Radio AGNs using LOFAR
Emmet Golden-Marx, Emily Moravec, Lu Shen +10
Bent radio AGN morphology depends on the density of the surrounding gas. However, bent sources are found inside and outside clusters, raising the question of how environment impact…
Circumgalactic Ly Nebulae in Overdense Quasar Pair Regions Observed with the Palomar Cosmic Web Imager
Jessica S. Li, Carlos J. Vargas, Donal O'Sullivan +8
The recent discovery of enormous Ly nebulae (ELANe), characterized by physical extents kpc and Ly luminosities erg s, provide a unique opportunity to…
Revealing the Gas Recycling in the Circumgalactic Medium (CGM) Utilizing a Luminous Ly Nebula Around a Type-II Quasar at z=2.6 with the Keck Cosmic Web Imager (KCWI)
Shiwu Zhang, Zheng Cai, Dandan Xu +7
How galaxies acquire material from the circumgalactic medium (CGM) is a key question in galaxy evolution. Recent observations and simulations show that gas recycling could be an im…
The luminosity-area relation of quasars' Ly nebulae
Fabrizio Arrigoni Battaia, Aura Obreja, Tiago Costa +2
Cool (~K) gas is commonly observed around quasars as traced by extended Ly emission. These large-scale nebulae are usually studied using circularly averaged sur…
JCMT/SCUBA-2 uncovers an excess of m counts on megaparsec scales around high-redshift quasars. Characterization of the overdensities and their alignment with the quasars' Ly nebulae
Fabrizio Arrigoni Battaia, Aura Obreja, Chian-Chou Chen +7
We conducted a systematic survey of the environment of high-z quasars at submillimeter wavelengths to unveil and characterize the surrounding distribution of dusty submillimeter ga…
Bubble in the Whale: Identifying the Optical Counterparts and Extended Nebula for the Ultraluminous X-ray Sources in NGC 4631
Jing Guo, Jianfeng Wu, Hua Feng +9
We present a deep optical imaging campaign on the starburst galaxy NGC 4631 with CFHT/MegaCam. By supplementing the HST/ACS and Chandra/ACIS archival data, we search for the optica…
An Hα Impression of Lyα Galaxies at with Deep JWST/NIRCam Imaging
Yuanhang Ning, Zheng Cai, Linhua Jiang +3
We present a study of seven spectroscopically confirmed (Ly emitting) galaxies at redshift using the /NIRCam imaging data. These galaxies, with a wide range of…
The physical origin for spatially large scatter of IGM opacity at the end of reionization: the IGM Ly opacity-galaxy density relation
Rikako Ishimoto, Nobunari Kashikawa, Daichi Kashino +9
The large opacity fluctuations in the Ly forest may indicate inhomogeneous progress of reionization. To explain the observed large scatter of the effective Ly optic…
The miniJPAS Survey: Detection of double-core Lyα morphology of two high-redshift (z>3) QSOs
P. T. Rahna, Zhen-Ya Zheng, Ana L. Chies-Santos +30
The Ly emission is an important tracer of neutral gas in a circum-galactic medium (CGM) around high-z QSOs. The origin of Lya emission around QSOs is still under debate which ha…
Reply to: Three papers regarding the origin of GN-z11-flash
Linhua Jiang, Shu Wang, Bing Zhang +8
In Jiang et al., we detected a bright flash (hereafter GN-z11-flash) that appeared as compact continuum emission during our Keck MOSFIRE observations of the galaxy GN-z11 at z ~ 11…
Mid-InfraRed Outbursts in Nearby Galaxies (MIRONG). II. Optical Spectroscopic Follow-up
Yibo Wang, Ning Jiang, Tinggui Wang +8
Infrared echo has proven to be an effective means to discover transient accretion events of supermassive black holes (SMBHs), such as tidal disruption events (TDEs) and changing-lo…
From large-scale environment to CGM angular momentum to star forming activities -- I: star-forming galaxies
Sen Wang, Dandan Xu, Shengdong Lu +5
The connection between halo gas acquisition through the circumgalactic medium (CGM) and galaxy star formation has long been studied. In this series of two papers, we put this inter…
More than softer-when-brighter: the X-Ray powerlaw spectral variability in NGC 4051
Yun-Jing Wu, Jun-Xian Wang, Zhen-Yi Cai +3
The powerlaw X-ray spectra of active galactic nuclei at moderate to high accretion rates normally appear softer when they brighten, for which the underlying mechanisms are yet uncl…
Gaia17biu/SN 2017egm in NGC 3191: The closest hydrogen-poor superluminous supernova to date is in a "normal", massive, metal-rich spiral galaxy
Subhash Bose, Subo Dong, A. Pastorello +55
Hydrogen-poor superluminous supernovae (SLSNe-I) have been predominantly found in low-metallicity, star-forming dwarf galaxies. Here we identify Gaia17biu/SN 2017egm as an SLSN-I o…
