Resolving the Assembly of Disk Galaxies from the Epoch of Reionisation to Cosmic Noon
Melanie Kaasinen, Mahsa Kohandel, Francesca Rizzo +45
Most of the mass and angular momentum of today's disk galaxies assembled at . Yet, it remains unclear how these galaxies acquired their gas, how their baryons and dark matter…
ALMA2040: Understanding the Early Assembly of Galaxies - The Formation of Star-Forming Clumps and their Role in Shaping Galaxy Evolution
Anita Zanella, Andreas L. Faisst, Rodrigo Herrera-Camus +25
Astrophysics seeks to explain how galaxies form and evolve through the interplay of stars, gas, and dust. Giant molecular clouds (GMCs), the main reservoirs and sites of star forma…
MUSE-DARK IV. Comparing Dark Matter Densities to Star Formation Histories in 375 intermediate-z galaxies
B. I. Ciocan, N. F. Bouché, J. Fensch +5
(Abridged) Baryonic feedback is expected to transform cuspy dark-matter (DM) haloes into cores, but direct observational links between inner DM slopes and galaxy star-formation his…
MUSE-DARK III: The evolution of the radial acceleration relation at intermediate redshifts
B. I. Ciocan, N. F. Bouché, J. Fensch +5
The radial acceleration relation (RAR) is a tight empirical correlation between the observed radial acceleration (a_tot) and the baryonic radial acceleration (a_bar) measured acros…
Dwarf galaxies in the MATLAS Survey: Hubble Space Telescope observations of nuclear star clusters
Mélina Poulain, Francine R. Marleau, Pierre-Alain Duc +8
In dwarf galaxies, nuclear star clusters (NSCs) are believed to primarily form from the migration and merger of globular clusters (GCs), with a possible contribution from in-situ s…
MUSE-DARK-I: Dark matter halo properties of intermediate-z star-forming galaxies
B. I. Ciocan, N. F. Bouché, J. Fensch +5
[Abridged] We analyse the dark matter (DM) halo properties of 127 0.3<z<1.5 star-forming galaxies (SFGs) down to low stellar masses (8<log(Mstar/Msun)<11), using data from the MUSE…
Evidence of star cluster migration and merger in dwarf galaxies
Mélina Poulain, Rory Smith, Pierre-Alain Duc +8
Nuclear star clusters (NSCs) are the densest stellar systems in the Universe. They can be found at the center of all galaxy types, but tend to favor galaxies of intermediate stella…
A mass invariant in a compressible turbulent medium
Pierre Dumond, Jérémy Fensch, Gilles Chabrier +1
Predicting the measurable statistical properties of density fluctuations in a supersonic compressible turbulent flow is a major challenge in physics. In 1951, Chandrasekhar derived…
Revisiting the globular clusters of NGC1052-DF2
K. Fahrion, M. A. Beasley, A. Gvozdenko +4
The ultra-diffuse galaxy (UDG) NGC1052-DF2 has captured the interest of astronomers ever since the low velocity dispersion measured from ten globular clusters (GCs) suggested a low…
Dwarf Galaxies in the MATLAS Survey: Hubble Space Telescope Observations of the Globular Cluster Systems of 74 Ultra Diffuse Galaxies
Francine R. Marleau, Pierre-Alain Duc, Melina Poulain +7
Ultra diffuse galaxies, characterized by their low surface brightness and large physical size, constitute a subclass of dwarf galaxies that challenge our current understanding of g…
Molecular and Ionized Gas in Tidal Dwarf Galaxies: The Spatially Resolved Star-Formation Relation
Navyasree Kovakkuni, Federico Lelli, Pierre-alain Duc +12
Tidal dwarf galaxies (TDGs) are low-mass objects that form within tidal and/or collisional debris ejected from more massive interacting galaxies. We use CO() observations from…
HI observations of the MATLAS dwarf and ultra-diffuse galaxies
Melina Poulain, Francine R. Marleau, Rebecca Habas +8
The presence of HI gas in galaxies is inextricably linked to their morphology and evolution. This paper aims to understand the HI content of the already identified 2210 dwarfs loca…
Origin of the spectacular tidal shells of galaxy NGC474
Michal Bílek, Jérémy Fensch, Ivana Ebrová +4
The lenticular galaxy NGC474 hosts a rich system of tidal shells and streams, some of which are exceptionally bright. Two teams recently presented spectroscopic observations of the…
Ultra diffuse galaxies in the MATLAS low-to-moderate density fields
Francine R. Marleau, Rebecca Habas, Melina Poulain +10
Recent advances in deep dedicated imaging surveys over the past decade have uncovered a surprisingly large number of extremely faint low surface brightness galaxies with large phys…
Stellar feedback in a clumpy galaxy at 3.4
E. Iani, A. Zanella, J. Vernet +18
Giant star-forming regions (clumps) are widespread features of galaxies at . Theory predicts that they can play a crucial role in galaxy evolution if they survive to…
