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…
The wide-field, multiplexed, spectroscopic facility WEAVE: Survey design, overview, and simulated implementation
Shoko Jin, Scott C. Trager, Gavin B. Dalton +212
WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, will see first light in late 2022. WEAVE comprises a new 2-degree…
Morphology driven evolution of barred galaxies in OMEGAWINGS Clusters
Amira A. Tawfeek, Bernardo Cervantes Sodi, Jacopo Fritz +6
We present a study of barred galaxies in the cluster environment, exploiting a sample of galaxies drawn from the extended WIde-field Nearby Galaxy-cluster Survey (OmegaWINGS) that…
Status of the PSF Reconstruction Work Package for MICADO ELT
Andrea Grazian, Matteo Simioni, Carmelo Arcidiacono +20
MICADO is a workhorse instrument for the ESO ELT, allowing first light capability for diffraction limited imaging and long-slit spectroscopy at near-infrared wavelengths. The PSF R…
BRUTE, PSF Reconstruction for the SOUL pyramid-based Single Conjugate Adaptive Optics facility of the LBT
Carmelo Arcidiacono, Andrea Grazian, Anita Zanella +11
The astronomical applications greatly benefit from the knowledge of the instrument PSF. We describe the PSF Reconstruction algorithm developed for the LBT LUCI instrument assisted…
LBT SOUL data as a science test bench for MICADO PSF-R tool
Matteo Simioni, Carmelo Arcidiacono, Roland Wagner +14
Current state-of-the-art adaptive optics (AO) provides ground-based, diffraction-limited observations with high Strehl ratios (SR). However, a detailed knowledge of the point sprea…
Point spread function reconstruction for SOUL+LUCI LBT data
Matteo Simioni, Carmelo Arcidiacono, Roland Wagner +14
This paper presents the status of an ongoing project aimed at developing a PSF reconstruction software for adaptive optics (AO) observations. In particular, we test for the first t…
GASP XXXIX: MeerKAT hunts Jellyfish in A2626
Tirna Deb, Marc A. W. Verheijen, Bianca M. Poggianti +14
We present MeerKAT HI observations of six jellyfish candidate galaxies (JFCGs) in the galaxy cluster, A2626. Two of the six galaxies JW100 and JW103, that were identified as JFCGs…
Walk on the Low Side: LOFAR explores the low-frequency radio emission of GASP jellyfish galaxies
Alessandro Ignesti, Benedetta Vulcani, Bianca M. Poggianti +13
Jellyfish galaxies, characterized by long filaments of stripped interstellar medium extending from their disks, are the prime laboratories to study the outcomes of ram pressure str…
Locations and Morphologies of Jellyfish Galaxies in A2744 and A370
C. Bellhouse, B. M. Poggianti, A. Moretti +11
We present a study of the orbits, environments and morphologies of 13 ram-pressure stripped galaxies in the massive, intermediate redshift (z) galaxy clusters A2744 an…
Unveiling the interplay between the GASP jellyfish galaxy JO194 and its environment with Chandra
Chiara Bartolini, Alessandro Ignesti, Myriam Gitti +8
X-ray studies of jellyfish galaxies opened a window in the physics of the interplay between intracluster medium (ICM) and interstellar medium (ISM). In this paper, we present the s…
A New Method to Constrain the Appearance and Disappearance of Observed Jellyfish Galaxy Tails
Rory Smith, Jong-Ho Shinn, Stephanie Tonnesen +11
We present a new approach to observationally constrain where the tails of Jellyfish (JF) galaxies in groups and clusters first appear and how long they remain visible with respect…
Post-starburst galaxies in the centers of intermediate redshift clusters
Ariel Werle, Bianca Poggianti, Alessia Moretti +17
We present results from MUSE spatially-resolved spectroscopy of 21 post-starburst galaxies in the centers of 8 clusters from to . We measure spatially resolved…
The relevance of ram pressure stripping for the evolution of blue cluster galaxies as seen at optical wavelengths
B. Vulcani, B. M. Poggianti, R. Smith +5
Ram pressure stripping is one of the most efficient mechanisms able to affect the gas reservoir in cluster galaxies and in the last decades many studies have characterized the prop…
GASP XXXVII: The Most Extreme Jellyfish Galaxies Compared to Other Disk Galaxies in Clusters, an HI Study
N. Luber, A. Müller, J. H. van Gorkom +19
We present the results of a VLA HI imaging survey aimed at understanding why some galaxies develop long extraplanar H tails, becoming extreme jellyfish galaxies. The observation…
