Tracing Galaxy Evolution in infalling galaxies of Abell 496: From Starburst to Quenching
M. M. López-Gutiérrez, H. Bravo-Alfaro, P. T. Rahna +4
During the fall of late-type galaxies into clusters, they can experiment a variety of evolutionary mechanisms according their local environment. Consequently, studying the UV emiss…
Systematic analysis of jellyfish galaxy candidates in Fornax, Antlia, and Hydra from the S-PLUS survey: A self-supervised visual identification aid
Yash Gondhalekar, Ana L. Chies-Santos, Rafael S. de Souza +22
We study 51 jellyfish galaxy candidates in the Fornax, Antlia, and Hydra clusters. These candidates are identified using the JClass scheme based on the visual classification of wid…
Study of Star-formation in Dual Nuclei Galaxies using UVIT observations
K. Rubinur, M. Das, P. Kharb +3
We have used the Ultraviolet Imaging Telescope (UVIT) aboard AstroSat to study star formation in a sample of nine dual nuclei galaxies with separations ~11 kpc, which is an expecte…
The Hubble Deep Hydrogen Alpha (HDH) Project: I. Catalog of Emission-line Galaxies
Shuairu Zhu, Zhen-Ya Zheng, James Rhoads +14
We present the first results of the Hubble Deep Hydrogen Alpha (HDH) project, which analyzes the space-borne deep H narrowband imaging data in the GOODS-S region. The HDH…
Strange Quasar Candidates with Abnormal Astrometric Characteristics from Gaia EDR3 and SDSS (SQUAB-II): Optical Identifications
Xiang Ji, Zhen-Ya Zheng, Qiqi Wu +7
There are some strange quasars with multiple Gaia detections or observed with abnormal astrometric characteristics, such as with large proper motions or significant astrometric noi…
The miniJPAS & J-NEP surveys: Identification and characterization of the Ly Emitter population and the Ly Luminosity Function
Alberto Torralba-Torregrosa, Siddhartha Gurung-López, Pablo Arnalte-Mur +27
We present the Lyman- (Lya) Luminosity Function (LF) at , estimated from a sample of 67 Lya-emitter (LAE) candidates in the J-PAS Pathfinder surveys: miniJPAS and J…
Discovery of Five Green Pea Galaxies with Double-peaked Narrow [OIII] Lines
Ruqiu Lin, Zhen-Ya Zheng, Jun-Xian Wang +9
Although double-peaked narrow emission-line galaxies have been studied extensively in the past years, only a few are reported with the green pea galaxies (GPs). Here we present our…
The miniJPAS survey: AGN & host galaxy co-evolution of X-ray selected sources
I. E. López, M. Brusa, S. Bonoli +35
Studies indicate strong evidence of a scaling relation in the local Universe between the supermassive black hole mass ($M_\rm{BH}$) and the stellar mass of their host galaxies ($M_…
On the Origin of the Strong Optical Variability of Emission-line Galaxies
Ruqiu Lin, Zhen-Ya Zheng, Weida Hu +9
Emission-line galaxies (ELGs) are crucial in understanding the formation and evolution of galaxies, while little is known about their variability. Here we report the study on the o…
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…
Simultaneous X-ray/UV observations of ultraluminous X-ray source Holmberg II X-1 with Indian space mission AstroSat
A. Vinokurov, K. Atapin, O. P. Bordoloi +11
We present the results of 8 epochs of simultaneous UV and X-ray observations of the highly variable ultraluminous X-ray source (ULX) Holmberg II X-1 with AstroSat -- Indian multiwa…
CDFS-6664: A candidate of Lyman-continuum Emission at z~3.8 detected by HDUV
Fang-Ting Yuan, Zhen-Ya Zheng, Ruqiu Lin +2
We report the detection of Lyman Continuum (LyC) emission from the galaxy, CDFS-6664, at z=3.797 in a sample of Lyman break galaxies with detected [OIII] emission lines. The LyC em…
A Comparison of the UV and HI Properties of the Extended UV (XUV) Disk Galaxies NGC 2541, NGC 5832 and ESO406-042
