Galaxy and Mass Assembly (GAMA): Extended Intra-Group Light in a group at from deep Hyper-Suprime Cam images
Cristina Martinez-Lombilla, Sarah Brough, Mireia Montes +7
We present a pilot study to assess the potential of Hyper Suprime-Cam Public Data Release 2 (HSC-PDR2) images for the analysis of extended faint structures within groups of galaxie…
A search for stellar tidal streams around Milky Way analogues from the SAGA sample
Juan Miro-Carretero, David Martinez-Delgado, Silvia Farras-Aloy +6
Context. Stellar tidal streams are the result of tidal interactions between a central galaxy and lower mass systems like satellite galaxies or globular clusters. For the Local Grou…
A giant umbrella-like stellar stream around the tidal ring galaxy NGC 922
David Martinez-Delgado, Santi Roca-Fabrega, Juan Miro-Carretero +6
Tidal ring galaxies are observed rarely in the local universe due to their intrinsically transient nature. The tidal ring structures are the result of strong interactions between g…
J-PLUS: Uncovering a large population of extreme [OIII] emitters in the local Universe
A. Lumbreras-Calle, C. López-Sanjuan, D. Sobral +17
Over the past decades, several studies have discovered a population of galaxies undergoing very strong star formation events, called extreme emission line galaxies (EELGs). In this…
Once in a blue stream: Detection of recent star formation in the NGC 7241 stellar stream with MEGARA
David Martinez-Delgado, Santi Roca-Fabrega, Armando Gil de Paz +23
In this work we study the striking case of a narrow blue stream around the NGC 7241 galaxy and its foreground dwarf companion. We want to figure out if the stream was generated by…
Introducing the LBT Imaging of Galactic Halos and Tidal Structures (LIGHTS) survey. A preview of the low surface brightness Universe to be unveiled by LSST
Ignacio Trujillo, Mauro D'Onofrio, Dennis Zaritsky +10
We present the first results of the LBT Imaging of Galaxy Haloes and Tidal Structures (LIGHTS) survey. LIGHTS is an ongoing observational campaign with the 2x8.4m Large Binocular T…
Hidden depths in the local Universe: The Stellar Stream Legacy Survey
David Martinez-Delgado, Andrew P. Cooper, Javier Roman +26
Mergers and tidal interactions between massive galaxies and their dwarf satellites are a fundamental prediction of the Lambda-Cold Dark Matter cosmology. These events are thought t…
MUSEQuBES: Calibrating the redshifts of Ly α emitters using stacked circumgalactic medium absorption profiles
Sowgat Muzahid, Joop Schaye, Raffaella Anna Marino +17
Lyman (Ly) emission lines are typically found to be redshifted with respect to the systemic redshifts of galaxies, likely due to resonant scattering of Ly photons. Here w…
Nearly all the sky is covered by Lyman-alpha emission around high redshift galaxies
L. Wisotzki, R. Bacon, J. Brinchmann +22
Galaxies are surrounded by large reservoirs of gas, mostly hydrogen, fed by inflows from the intergalactic medium and by outflows due to galactic winds. Absorption-line measurement…
The MUSE Hubble Ultra Deep Field Survey VIII : Extended Lyman-alpha haloes around high-redshift star-forming galaxies
Floriane Leclercq, Roland Bacon, Lutz Wisotzki +17
We report the detection of extended Lyman-alpha (Lya) haloes around 145 individual star-forming galaxies at redshifts 3<z<6 in the Hubble Ultra Deep Field observed with the Multi-U…
The MUSE Hubble Ultra Deep Field Survey: II. Spectroscopic redshifts and comparisons to color selections of high-redshift galaxies
H. Inami, R. Bacon, J. Brinchmann +22
We have conducted a two-layered spectroscopic survey (1'x1' ultra deep and 3'x3' deep regions) in the Hubble Ultra Deep Field (HUDF) with the Multi Unit Spectroscopic Explorer (MUS…
The MUSE Hubble Ultra Deep Field Survey: I. Survey description, data reduction and source detection
Roland Bacon, Simon Conseil, David Mary +24
We present the MUSE Hubble Ultra Deep Survey, a mosaic of nine MUSE fields covering 90\% of the entire HUDF region with a 10-hour deep exposure time, plus a deeper 31-hour exposure…
Great Optically Luminous Dropout Research Using Subaru HSC (GOLDRUSH). I. UV Luminosity Functions at Derived with the Half-Million Dropouts on the 100 deg Sky
Yoshiaki Ono, Masami Ouchi, Yuichi Harikane +23
We study the UV luminosity functions (LFs) at , , and based on the deep large-area optical images taken by the Hyper Suprime-Cam (HSC) Subaru strategic program…
