We present findings of 3D filamentary structures in the Smith Cloud, a high-velocity cloud (HVC) located at , . We use data from the Galactic Arecibo L…
A Milky Way-like barred spiral galaxy at a redshift of 3
Luca Costantin, Pablo G. Pérez-González, Yuchen Guo +30
The majority of massive disk galaxies in the local Universe show a stellar barred structure in their central regions, including our Milky Way. Bars are supposed to develop in dynam…
High-Spectral Resolution Observations of the Optical Filamentary Nebula in NGC 1275
Benjamin Vigneron, Julie Hlavacek-Larrondo, Carter Lee Rhea +18
We present new high-spectral resolution observations (R = = 7000) of the filamentary nebula surrounding NGC 1275, the central galaxy of the Perseus cluster. These observatio…
The influence of globular cluster evolution on the specific frequency in dwarf galaxies
Elizabeth Moreno-Hilario, Luis A. Martinez-Medina, Hui Li +2
Dwarf galaxies are known to exhibit an unusual richness in numbers of globular clusters (GCs), property quantified by the specific frequency (), which is high for dwarf and gi…
JWST Reveals Widespread AGN-Driven Neutral Gas Outflows in Massive z ~ 2 Galaxies
Rebecca L. Davies, Sirio Belli, Minjung Park +15
We use deep JWST/NIRSpec R~1000 slit spectra of 113 galaxies at 1.7 < z < 3.5, selected from the mass-complete Blue Jay survey, to investigate the prevalence and typical properties…
Dissociative Recombination of Rotationally Cold OH and Its Implications for the Cosmic Ray Ionization Rate in Diffuse Clouds
Ábel Kálosi, Lisa Gamer, Manfred Grieser +12
Observations of OH are used to infer the interstellar cosmic ray ionization rate in diffuse atomic clouds, thereby constraining the propagation of cosmic rays through and the s…
The Kinematic Structure of Magnetically Aligned HI Filaments
Doyeon Avery Kim, Susan E Clark, Mary E Putman +1
We characterize the kinematic and magnetic properties of HI filaments located in a high Galactic latitude region ( and ). We extra…
Simulating ionization feedback from young massive stars: impact of numerical resolution
Yunwei Deng, Hui Li, Rahul Kannan +3
Modelling galaxy formation in hydrodynamic simulations has increasingly adopted various radiative transfer methods to account for photoionization feedback from young massive stars.…
Pre-supernova feedback sets the star cluster mass function to a power law and reduces the cluster formation efficiency
Eric P. Andersson, Mordecai-Mark Mac Low, Oscar Agertz +2
The star cluster initial mass function is observed to have an inverse power law exponent around 2, yet there is no consensus on what determines this distribution, and why some vari…
Star Formation Shut Down by Multiphase Gas Outflow in a Galaxy at a Redshift of 2.45
Sirio Belli, Minjung Park, Rebecca L. Davies +15
Large-scale outflows driven by supermassive black holes are thought to play a fundamental role in suppressing star formation in massive galaxies. However, direct observational evid…
Cosmological baryon spread and impact on matter clustering in CAMELS
Matthew Gebhardt, Daniel Anglés-Alcázar, Josh Borrow +9
We quantify the cosmological spread of baryons relative to their initial neighboring dark matter distribution using thousands of state-of-the-art simulations from the Cosmology and…
Roman Early-Definition Astrophysics Survey Opportunity: Galactic Roman Infrared Plane Survey (GRIPS)
Roberta Paladini, Catherine Zucker, Robert Benjamin +67
A wide-field near-infrared survey of the Galactic disk and bulge/bar(s) is supported by a large representation of the community of Galactic astronomers. The combination of sensitiv…
Structure, Kinematics, and Observability of the Large Magellanic Cloud's Dynamical Friction Wake in Cold vs. Fuzzy Dark Matter
Hayden R. Foote, Gurtina Besla, Philip Mocz +7
The Large Magellanic Cloud (LMC) will induce a dynamical friction (DF) wake on infall to the Milky Way (MW). The MW's stellar halo will respond to the gravity of the LMC and the da…
Galactic coronae in Milky Way-like galaxies: the role of stellar feedback in gas accretion
Filippo Barbani, Raffaele Pascale, Federico Marinacci +4
Star-forming galaxies like the Milky Way are surrounded by a hot gaseous halo at the virial temperature - the so-called galactic corona - that plays a fundamental role in their evo…
A Pulsar-Based Map of Galactic Acceleration
Abigail Moran, Chiara M. F. Mingarelli, Ken Van Tilburg +1
Binary pulsars can be used to probe Galactic potential gradients through calculating their line-of-sight accelerations. We present the first data release of direct line-of-sight ac…
Energy Flux and Particle Flux in Steady-State Solutions of Nuclear Star Clusters
Barak Rom, Itai Linial, Re'em Sari
We examine the effects of two-body interactions in a nuclear star cluster surrounding a supermassive black hole. We evaluate the energy flux, analogously to the particle flux calcu…
The impact of early massive mergers on the chemical evolution of Milky Way-like galaxies: insights from NIHAO-UHD simulations
Tobias Buck, Aura Obreja, Bridget Ratcliffe +4
Recent observations of the Milky Way (MW) found an unexpected steepening of the star-forming gas metallicity gradient around the time of the Gaia-Sausage-Enceladus (GSE) merger eve…
HSC-CLAUDS survey: The star formation rate functions since z ~ 2 and comparison with hydrodynamical simulations
V. Picouet, S. Arnouts, E. Le Floch +16
Star formation rate functions (SFRFs) give an instantaneous view of the distribution of star formation rates (SFRs) in galaxies at different epochs. They are a complementary and mo…
