Galaxy mass dependence of metal-enrichment of nuclear star clusters

Wenhe Lyu, Hong-Xin Zhang, Sanjaya Paudel +5

Nuclear Star Clusters (NSCs) are commonly found in galaxy centers, but their dominant formation mechanisms remain elusive. We perform a consistent analysis of stellar populations o…

Detection of an orthogonal alignment between parsec scale AGN jets and their host galaxies

D. Fernández Gil, J. A. Hodgson, B. L'Huillier +6

The relationship between galaxies and their supermassive black holes (SMBHs) is an area of active research. One way to investigate this is to compare parsec-scale jets formed by SM…

Dwarf Galaxies in the MATLAS Survey: The satellite system of NGC474 under scrutiny with MUSE

Oliver Müller, Francine R. Marleau, Nick Heesters +12

A recent study of the distribution of dwarf galaxies in the MATLAS sample in galaxy groups revealed an excess of flattened satellite structures, reminiscent of the co-rotating plan…

Moving Groups in the Solar Neighborhood with Gaia, APOGEE, GALAH, and LAMOST: Dynamical Effects Gather Gas and the Ensuing Star Formation Plays an Important Role in Shaping the Stellar Velocity Distributions

Xilong Liang, Suk-Jin Yoon, Jingkun Zhao

With Gaia, APOGEE, GALAH, and LAMOST data, we investigate the positional, kinematic, chemical, and age properties of nine moving groups in the solar neighborhood. We find that each…

Kilogauss magnetic field and jet dynamics in the quasar NRAO 530

Mikhail Lisakov, Svetlana Jorstad, Maciek Wielgus +12

The advancement of the Event Horizon Telescope has enabled the study of relativistic jets in active galactic nuclei down to sub-parsec linear scales even at high redshift. Quasi-si…

Tracing the Formation History of Intrahalo Light with Horizon Run 5

Hyungjin Joo, M. James Jee, Juhan Kim +8

We investigate the formation history of intrahalo light (IHL) using the high-resolution (~1 kpc), large-scale (~Gpc) cosmological hydrodynamical simulation, Horizon Run 5 (HR5). IH…

On the original composition of the gas forming first-generation stars in clusters: insights from HST and JWST

M. V. Legnardi, A. P. Milone, G. Cordoni +8

Globular cluster (GC) stars composed of pristine material (first-generation, 1G, stars) are not chemically homogeneous, as they exhibit extended sequences in the "Chromosome Map" (…

The Effect of Cosmic Rays on the Observational Properties of the CGM

Daniel DeFelippis, Frédéric Bournaud, Nicolas F. Bouché +5

The circumgalactic medium (CGM) contains information on the cumulative effect of galactic outflows over time, generally thought to be caused by feedback from star formation and act…

The SAMI Galaxy Survey: galaxy spin is more strongly correlated with stellar population age than mass or environment

S. M. Croom, J. van de Sande, S. P. Vaughan +17

We use the SAMI Galaxy Survey to examine the drivers of galaxy spin, , in a multi-dimensional parameter space including stellar mass, stellar population age (or specific s…

The SAMI Galaxy Survey: Using Tidal Streams and Shells to Trace the Dynamical Evolution of Massive Galaxies

Tomas H. Rutherford, Jesse van de Sande, Scott M. Croom +14

Slow rotator galaxies are distinct amongst galaxy populations, with simulations suggesting that a mix of minor and major mergers are responsible for their formation. A promising pa…

Galaxies with grains: unraveling dust evolution and extinction curves with hydrodynamical simulations

Yohan Dubois, Francisco Rodríguez Montero, Corentin Guerra +6

We introduce a model for dust evolution in the RAMSES code for simulations of galaxies with a resolved multiphase interstellar medium. Dust is modelled as a fluid transported with…

The Energy and Dynamics of Trapped Radiative Feedback with Stellar Winds

Sam Geen, Rebekka Bieri, Alex de Koter +2

In this paper, we explore the significant, non-linear impact that stellar winds have on H ii regions. We perform a parameter study using three-dimensional radiative magnetohydrodyn…

Cosmic evolution of black hole-spin and galaxy orientations: clues from the NewHorizon and Galactica simulations

Sebastien Peirani, Yasushi Suto, Ricarda S. Beckmann +10

(Reduced) Using the recent cosmological high-resolution zoom-in simulations, NewHorizon and Galactica, in which the evolution of black hole spin is followed on the fly, we have tra…
