ViCTORIA project: MeerKAT HI observations of the ram pressure stripped galaxy NGC 4523
A. Boselli, P. Serra, F. de Gasperin +22
We present the first results of a 21 cm HI line pilot observation carried out with MeerKAT in preparation for the ViCTORIA project, an untargeted survey of the Virgo galaxy cluster…
Metallicity Distribution Functions of 13 Ultra-Faint Dwarf Galaxy Candidates from Hubble Space Telescope Narrowband Imaging
Sal Wanying Fu, Daniel R. Weisz, Else Starkenburg +10
We present uniformly measured stellar metallicities for 463 stars in 13 Milky Way (MW) ultra-faint dwarf galaxies (UFDs; to ) using narrowband CaHK (F395N) imagi…
The Next Generation Virgo Cluster Survey (NGVS). XXXV. First Kinematical Clues of Overly-Massive Dark Matter Halos in Several Ultra-Diffuse Galaxies in the Virgo Cluster
Elisa Toloba, Laura V. Sales, Sungsoon Lim +8
We present Keck/DEIMOS spectroscopy of the first complete sample of ultra-diffuse galaxies (UDGs) in the Virgo cluster. We select all UDGs in Virgo that contain at least 10 globula…
UVIT view of NGC 5291: Ongoing star formation in tidal dwarf galaxies at ~ 0.35 kpc resolution
Rakhi R, Geethika Santhosh, Prajwel Joseph +14
NGC 5291, an early-type galaxy surrounded by a giant HI ring, is believed to be formed from collision with another galaxy. Several star forming complexes and tidal dwarf galaxies a…
Ultraviolet imaging observations of three jellyfish galaxies: Star formation suppression in the centre and ongoing star formation in stripped tails
Koshy George, B. M. Poggianti, Neven Tomičić +13
Spiral galaxies undergo strong ram-pressure effects when they fall into the galaxy cluster potential. As a consequence, their gas is stripped to form extended tails within which st…
Globular Cluster UVIT legacy Survey (GlobUleS) III. Omega Centauri in Far-Ultraviolet
Deepthi S. Prabhu, Annapurni Subramaniam, Snehalata Sahu +21
We present the first comprehensive study of the most massive globular cluster Omega Centauri in the far-ultraviolet (FUV) extending from the center to ~ 28% of the tidal radius usi…
Deepest far ultraviolet view of a central field in the Coma cluster by AstroSat UVIT
Smriti Mahajan, Kulinder Pal Singh, Joseph E. Postma +3
We present analysis of the far ultraviolet (FUV) emission of sources in the central region of the Coma cluster (z=0.023) using the data taken by the UVIT aboard the multi-wavelengt…
The Spectroscopy and H-band Imaging of Virgo cluster galaxies (SHIVir) Survey: Data Catalogue and Kinematic Profiles
Nathalie N. -Q. Ouellette, Stéphane Courteau, Jon A. Holtzman +10
The ``Spectroscopy and H-band Imaging of Virgo cluster galaxies'' (SHIVir) survey is an optical and near-infrared survey which combines SDSS photometry, deep H-band photometry, and…
The Color Gradients of the Globular Cluster Systems in M87 and M49
Yiming Wu, Chengze Liu, Eric W. Peng +8
Combining data from the ACS Virgo Cluster Survey (ACSVCS) and the Next Generation Virgo cluster Survey (NGVS), we extend previous studies of color gradients of the globular cluster…
The Distance and Dynamical History of the Virgo Cluster Ultradiffuse Galaxy VCC 615
J. Christopher Mihos, Patrick R. Durrell, Elisa Toloba +6
We use deep Hubble Space Telescope imaging to derive a distance to the Virgo Cluster ultradiffuse galaxy (UDG) VCC 615 using the tip of the red giant branch (TRGB) distance estimat…
The Next Generation Fornax Survey (NGFS): III. Revealing the Spatial Substructure of the Dwarf Galaxy Population inside half of Fornax's Virial Radius
Y. Ordenes-Briceño, P. Eigenthaler, M. A. Taylor +15
We report the discovery of 271 previously undetected dwarf galaxies in the outer Fornax cluster regions at radii using data from the Next Genera…
The Next Generation Virgo Cluster Survey. VII. The intrinsic shapes of low-luminosity galaxies in the core of the Virgo cluster, and a comparison with the Local Group
R. Sanchez-Janssen, L. Ferrarese, L. A. MacArthur +17
(Abridged) We investigate the intrinsic shapes of low-luminosity galaxies in the central 300 kpc of the Virgo cluster using deep imaging obtained as part of the NGVS. We build a sa…
The ACS Fornax Cluster Survey. IX. The Color-Magnitude Relation of Globular Cluster Systems
S. Mieske, A. Jordan, P. Cote +8
We investigate the color-magnitude relation for globular clusters (GCs) -- the so-called "blue tilt" -- detected in the ACS Fornax Cluster Survey and using the combined sample of G…
The Nature of the Red Giant Branches in the Ursa Minor and Draco Dwarf Spheroidal Galaxies
M. D. Shetrone, P. Cote, P. B. Stetson
Spectra for stars located redward of the fiducial red giant branches of the Ursa Minor and Draco dwarf spheroidal galaxies have been obtained with the Hobby-Eberly telescope and th…
A New Spin on the Problem of HB Gaps: Stellar Rotation along the Blue Horizontal Branch of Globular Cluster M13
Bradford B. Behr, S. G. Djorgovski, Judith G. Cohen +4
We have determined the projected rotational velocities of thirteen blue horizontal-branch (BHB) stars in the globular cluster M13 via rotational broadening of metal absorption line…
