The nearby Type II supernova 2024ggi beyond 600 days: circumstellar interaction and dust formation
The Type II SN 2024ggi is one of the nearest core-collapse SNe to have exploded in recent decades.Interpreting the stacked kinetic SZ signal II: the degeneracy between satellite galaxies and baryonic feedback
The kinetic Sunyaev-Zel'dovich (kSZ) signal stacked around a galaxy sample traces the gas around halos and is a powerful probe of baryonic feedback.MRI Turbulence versus $α$-Viscosity in Circumbinary Disks: Implications for Gravitational-Wave Dephasing and Accretion Variability
Our understanding of gas torques on massive black hole binaries (MBHBs) relies on hydrodynamical (HD) simulations of circumbinary disks (CBDs) in which an $α$-viscosity models angular momentum…Magnetic field evolution in feedback-dominated galaxies
Over the last decade, magnetic fields (B-fields) have become a common ingredient in galaxy formation simulations.From Giant Envelopes to Rapidly Contracting Cores in Rotating Population III Stars from $500$ to $1000 \, M_\odot$
Population III (Pop III) stars link the chemical enrichment of the early Universe to the formation of the first massive black holes, yet their evolution remains poorly understood at extreme masses.Scaling Up: A Global Optical/X-ray Correlation For Reprocessing Across Black Hole Masses
This study extends the optical/X-ray correlation from black hole low-mass X-ray binaries (XRBs) to active galactic nuclei (AGN), bridging scales from stellar-mass to supermassive black holes (SMBHs).An upper limit on Galactic OB+black hole binaries from SDSS-V
Binaries composed of a luminous OB star and a black hole (BH) are a key evolutionary link between massive stellar binaries and merging compact-object binaries, but only a handful are known and their…Physical characteristics of the Galaxy defining the oscillation period of librating orbits near the OLR of the bar
We studied librating orbits of stars near the Outer Lindblad Resonance (OLR) of the bar using the angle-action variables of Hamiltonian dynamics.Intermittency in the Multiphase ISM --- I. Extreme Density, Velocity, and Magnetic Fluctuations
Intermittency is a fundamental property of astrophysical turbulence because it concentrates strong gradients, dissipation, and transport into rare, localized structures.Untangling Similarities and Differences in Star Formation Histories Across Cosmological Simulations
How galaxies assemble depends on processes ranging from small-scale baryonic physics to large-scale cosmological assembly, which are difficult to disentangle with observations alone.Intermittency in the Multiphase ISM --- II. Non-Gaussian Dust Polarization and Foreground Variance
Interstellar turbulence produces non-Gaussian polarized Galactic dust emission whose higher-order statistics depend on thermal phase and turbulent forcing.Henrietta Leavitt's classical Cepheid relation
The Leavitt & Pickering (1912) mean period-magnitude relation for SMC Cepheids exhibits correlated residuals relative to modern Gaia $B_G$ and Johnson $V$ photometry ($r_{δV/δL12}\approx0.76$).Anisotropic Radiation in Super-Eddington Active Galactic Nuclei: The Responsivity of Broad-Line Regions to Continuum Variability
Anisotropic ionizing radiation is a natural theoretical expectation for super-Eddington accretion in active galactic nuclei (AGNs), implying that the ionizing flux incident on the broad-line region…Modelling the broken age-[Fe/H] relation and metallicity distribution function of mono-age populations
This study investigates the chemical evolution history and radial migration in the Milky Way utilizing high-precision age measurements based on large-scale stellar spectroscopic surveys.The Tilt of the Velocity Ellipsoid in the Milky Way Disk with GALAH-Gaia Data
We investigate the metallicity dependence of the tilt of the velocity ellipsoid using more than 572,000 stars selected from GALAH and Gaia.The DAWN JWST Archive: A spectroscopically-informed population study of the physical properties of galaxies at z>2
Charting the evolution of star-formation, stellar mass and dust build-up over cosmic time relies on the accurate characterisation of the stellar population properties of high redshift galaxies.An asteroseismic age estimate for the Pleiades using a neural-network emulator of rotating $δ$ Scuti pulsation models
Asteroseismology of $δ$ Sct stars has strong potential for determining the ages of young stars through individual mode fitting.Constraints on the r-process Delay Time from Dwarf Spheroidal Galaxies
The ancient stellar populations and simple structure of the local dwarf spheroidal galaxies (dSphs) make them excellent laboratories for studying the chemical evolution of the early universe.Beyond the Damped Random Walk: Multiband AGN Variability from SDSS to Rubin LSST
The flux variability of Active Galactic Nuclei (AGNs) is commonly modeled using the damped random walk (DRW), but increasingly rich multiband time-domain surveys motivate more flexible stochastic…Multiphase Analysis of (U)LIRG Nuclear Activity (MAUNA). I. Spatially Resolved Optical Emission-Line Diagnostics
We present resolved optical integral-field spectroscopy of the 32 luminous and ultraluminous infrared galaxy systems of the Multiphase Analysis of (U)LIRG Nuclear Activity (MAUNA) sample, drawn from…
