Is Abell 2261 a fossil galaxy cluster in a transitional dynamical state?
Hyowon Kim, Jongwan Ko, Rory Smith +5
Abell 2261 (A2661) is a well-studied fossil cluster, but previous studies give contradictory results on its dynamical states, such as its X-ray central entropy and magnitude gap. T…
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…
Exploring the AGN-ram pressure stripping connection in local clusters
Giorgia Peluso, Benedetta Vulcani, Bianca M. Poggianti +8
Ram-pressure stripping by the intracluster medium (ICM) is one of the most advocated mechanisms that affect the properties of cluster galaxies. A recent study based on a small samp…
Evidence for mixing between ICM and stripped ISM by the analysis of the gas metallicity in the tails of jellyfish galaxies
Andrea Franchetto, Stephanie Tonnesen, Bianca M. Poggianti +11
Hydrodynamical simulations show that the ram-pressure stripping in galaxy clusters fosters a strong interaction between stripped interstellar medium (ISM) and the surrounding mediu…
VERTICO: The Virgo Environment Traced In CO Survey
Toby Brown, Christine D. Wilson, Nikki Zabel +33
We present the Virgo Environment Traced in CO (VERTICO) survey, a new effort to map CO(), CO(), and CO() in 51 Virgo Cluster galaxies with the A…
The Galaxy Replacement Technique (GRT): a New Approach to Study Tidal Stripping and Formation of Intracluster Light in a Cosmological Context
Kyungwon Chun, Jihye Shin, Rory Smith +2
We introduce the Galaxy Replacement Technique (GRT) that allows us to model tidal stripping of galaxies with very high-mass (m~M/h) and high-spa…
Brought to Light II: Revealing the Origins of Cloaked Spiral Features in Cluster Passive Dwarf Galaxies
Rory Smith, Josefina Michea, Anna Pasquali +8
In our companion paper (Brought to Light I: Michea et al. 2021), we reveal spectacular spiral galaxy-like features in deep optical imaging of nine Virgo early-type dwarf galaxies,…
Brought to Light I: Quantification of Disk Substructure in Dwarf Early-Type Galaxies
Josefina Michea, Anna Pasquali, Rory Smith +4
Dwarf early-type galaxies (ETGs) display a rich diversity in their photometric, structural, and dynamical properties. In this work, we address their structural complexity by studyi…
The SAMI Galaxy Survey: Kinematics of stars and gas in brightest group galaxies; the role of group dynamics
Mojtaba Raouf, Rory Smith, Habib G. Khosroshahi +17
We study the stellar and gas kinematics of the brightest group galaxies (BGGs) in dynamically relaxed and unrelaxed galaxy groups for a sample of 154 galaxies in the SAMI galaxy su…
The Sami Galaxy Survey: stellar populations of passive spiral galaxies in different environment
Mina Pak, Sree Oh, Joon Hyeop Lee +17
We investigate the stellar populations of passive spiral galaxies as a function of mass and environment, using integral field spectroscopy data from the Sydney-AAO Multi-object Int…
GASP XXIX -- Unwinding the arms of spiral galaxies via ram-pressure stripping
Callum Bellhouse, Sean L. McGee, Rory Smith +11
We present the first study of the effect of ram-pressure "unwinding" the spiral arms of cluster galaxies. We study 11 ram-pressure stripped galaxies from GASP (GAs Stripping Phenom…
Beyond halo mass: quenching galaxy mass assembly at the edge of filaments
Hyunmi Song, Clotilde Laigle, Ho Seong Hwang +6
We examine how the mass assembly of central galaxies depends on their location in the cosmic web. The HORIZON-AGN simulation is analysed at z~2 using the DISPERSE code to extract m…

Revealing the formation mechanism of the shell galaxy NGC474 with MUSE
Jeremy Fensch, Pierre-Alain Duc, Sungsoon Lim +6
Stellar shells around galaxies could provide precious insights into their assembly history. However, their formation mechanism remains poorly empirically constrained, in particular…
