Hot off the Stacks: X-rays in Romulus25, Part I - Comparisons to Observations from eRosita
Recent observations from the from Spectrum Roentgen Gamma (SRG)/eROSITA all-sky survey data have helped to illuminate the hot circumgalactic medium (CGM) around galaxies at Milky Way-masses and above.Resolving the thermal component of stellar feedback with the "anchor-and-refine" scheme in galactic simulations
(abridged) Stellar feedback regulates galactic baryon cycles, but galaxy-scale simulations often cannot resolve supernova cooling radii.Extra! Extra! X-ray Emission!: X-rays in Romulus25, Part II - Physical Drivers of X-ray Emission in the CGM
Characterizing the hot (T ~ 10$^{6}$ K) circumgalactic medium (CGM) around Milky Way-mass (MW-mass) galaxies is critical to a full understanding of galaxy evolution.Not so dead after all: young stars in the massive S0 NGC 3115
Massive early-type galaxies (ETGs) are traditionally considered "red-and-dead" based on optical observations.Ejected and Rejected: Strong Scatterings in Dense Star Clusters
Understanding the evolution of collisional stellar systems is key to predicting both the bulk evolution of dense star clusters and also the rates of tidal disruption events, extreme mass ratio…Simulation-Informed Dust Masses in Typical $6<z<14$ JWST Galaxies
Direct detections of dust in typical $z>8$ galaxies remain untenable, despite the presence of dust suggested by rest-frame UV/optical spectro-photometry.Combining Multiple Incomplete Astronomical Surveys to Estimate Galaxy Flux Distributions
In astrophysics, the distributions of fluxes or intensities of populations of sources provide insight into the structure and evolution of the universe.No Significant Excess in Typical Variability in CLAS+ Changing-Look AGN Candidates in Rubin DP2
Rubin Data Preview 2 (DP2) samples the CLAS+ changing-look AGN (CLAGN) candidates $\sim1,000-9,000$ days after their comparison epochs, so it can test whether these objects retain enhanced…Validating an X-ray-based method for identifying Fermi blazars
Blazars are the main population of active galactic nuclei (AGNs) detected in gamma rays by Fermi.Simulating and Characterizing Non-Gaussian Small-Scale Polarized Emission
Galactic foregrounds present a major challenge for cosmic microwave background (CMB) cosmology as their amplitudes exceed the target primordial $B$-mode signal.The Carousel Lens III: Joint lens convergence and source kinematic modeling
We introduce a new, independent modeling component to the Carousel Lens series by exploiting the spatially-resolved kinematics contained within the lensed arcs, which so far has remained rather…Tidal shells as clocks of galaxy mergers and tests of cosmological models
Stellar shells-concentric arc-like tidal features formed in galaxy mergers-provide a valuable record of recent galaxy assembly histories encoding both the merger event and the gravitational…Cosmic rays in galaxy halos I: the circumgalactic transport rate and a dynamically significant cosmic-ray reservoir
Fermi-LAT observations imply that most of the cosmic rays (CRs) produced in normal star-forming galaxies escape from the discs where they are accelerated into the circumgalactic medium (CGM), but…ODIN: Comparison of Source Extractor and Tractor Source Detection for Lyman Alpha Emitting Galaxy Selection at z=3.1
Lyman Alpha Emitting galaxies (LAEs) are young, actively star-forming galaxies identified by their strong Lyman-alpha emission at a rest-frame wavelength of 121.6 nm, making them valuable tracers of…Radio view of the Peanut cluster: merger-induced stripping and a radio halo shortly after pericentric passage
The Peanut galaxy cluster (SRGe CL0238.3+2005) offers a rare opportunity to investigate thermal and nonthermal processes only $\sim0.1$\,Gyr after pericentric passage.Gaia DR3 Compact Binary Candidates Constrained by Radial Velocity Measurements
Astrometry enables the most direct determination of the orbital elements and component masses of compact binaries.Power spectrum of longitudinal-velocity residuals in the Galactic disk from Gaia DR3 red-giant-branch stars
Non-axisymmetric structures in the Galaxy produce coherent stellar motions in the Galactic disk.How Quickly Did the Giants Form? Constraining the Formation Timescales of Massive Quiescent Galaxies at Cosmic Noon Using Chemical Evolution Modelling
Massive quiescent galaxies (MQGs; $M_\star \sim 10^{11} \, \mathrm{M_\odot}$) at cosmic noon ($z \sim 2$) host $α$-enhanced stellar populations ($\mathrm{[Mg/Fe]} \sim 0.4 - 0.5$) at near-solar…Multiplicity of Massive stars in the Milky Way (M3W). II. The brightest single O stars: variability and systemic velocities
(ABRIDGED) M3W studies the dynamical properties of massive stars in the solar vicinity, such as their systemic velocities, which are affected by variability effects: pulsations, line infilling by…Linking Detectable Tidal Features to Stellar Halo Growth: An Integrated Analysis of the Outskirts of Massive Early-type Galaxies
Motivated by the finding that massive galaxies with tidal features (GwT) are preferentially found in low-density environments, one wonders whether this trend arises from enhanced debris…
