Multi-epoch monitoring of the faint northern component in 3C 84 during 2016-2021
We present the results of multi-epoch very long baseline interferometry (VLBI) observations of the sub-parsec-scale northern jet component of 3C 84 (known as the N1 component) at 7 mm from 2016 to…Unsupervised Neural Operators for Rotating Relativistic Stars: High-Fidelity Equation of State Inference and Pulsar Spin Evolution at Scale
Observed populations of rotating neutron stars~(NSs) with millisecond-order periods are powerful probes of fundamental physics.The kinematic Kelvin-Helmholtz instability-driven dynamo: implications for merging compact objects
Binary neutron star (BNS) mergers excite a Kelvin--Helmholtz instability (KHI) in the shear layer between them.The Environment of High-Energy Transient Host Galaxies at High Redshifts as Observed by SHARP
The study of transient events, such as Gamma-Ray Bursts (GRBs) and extreme Supernovae (SNe), provides a unique probe of star-forming environments in the early Universe.Black Hole Seeds and Little Red Dots: Connecting Formation and Growth with a JWST Multi-Cycle Treasury Program
JWST has revealed an abundant population of faint active galactic nuclei and a new class of compact, high-redshift sources known as Little Red Dots (LRDs), whose physical nature remains debated…Probing Dark Matter-Electron Scattering with the Central Molecular Zone
The Central Molecular Zone, a dense and gas-rich region surrounding the Galactic Center, hosts numerous dense molecular gas cores that provide unique environments to probe dark matter interactions.A Machine Learning Approach to Coupling Photoionization & Multi-Frequency Radiation Hydrodynamics
We use machine learning (ML) to couple photoionization microphysics to radiation hydrodynamic simulations of line-driven winds.Extreme Multiwavelength Variability in the Recurrent Intermediate-type Changing-look Seyfert Galaxy SDSS J234728.73+242745.7
We report the discovery of the Seyfert galaxy J234728.73+242745.7 as a recurrent intermediate-type CLAGN with extreme optical/UV variability.Chemical abundances of a Galactic Centre ejecta discovered in DESI
Chemical abundances in the Galactic Centre (GC) are challenging to measure because of high extinction, crowding, and distance, and are typically limited to the brightest AGB and M giants observed in…Two Fast Radio Burst Candidates Detected in the RATAN-600 Blind Survey
We report the detection of two single dispersed pulses with widths of about 6.7\,ms and 15.6\,ms and flux densities of about 0.8 and 1.7\,Jy.Decomposition of disk and jet optical emission: Case of PKS~1510-089 and PKS~0736+017
Measuring BLR size and black hole mass of jetted quasars with strong radio emission is challenging due to the contribution from non-thermal synchrotron radiation from the jet in the optical continuum.Jets and winds from the most powerful compact object in NGC 5408
Super-critical accretion onto stellar-mass compact objects is sometimes revealed by ultraluminous X-ray sources (ULXs).Surface Nitrogen enrichment from the LMC to the Early Universe: the roles of rotation, overshooting and mass loss
The strong nitrogen (N) features observed in high-redshift galaxies, such as GN-z11, with JWST point to an efficient source of N production in the early Universe.Galactic-Scale Distribution of 10Be and Its Implications for the Early Solar System 10Be/9Be
Meteoritic inclusions indicate that the early Solar System contained a substantial abundance of the short-lived radionuclide 10Be.H 0557$-$385: A Candidate Missing Link Between Radio-Quiet Seyferts and Young Radio Galaxies
The Seyfert 1 galaxy H 0557$-$385 (z = 0.034) has long been classified as radio-quiet on the basis of its radio-to-optical flux ratio, yet its radio properties are physically inconsistent with this…As a matter of reconstruction -- varying the magnetic Prandtl number in implicit large eddy simulations
The magnetic Prandtl number ($\mathrm{Pm}$), the ratio of viscosity to magnetic diffusivity, spans many orders of magnitude in astrophysical plasmas.Formation of Micron-sized Presolar Graphite Grains in Low-energy Supernova Ejecta
Presolar graphite grains with supernova isotopic signatures provide direct evidence that large graphite grains formed in supernova ejecta.Hidden Neutrino Active Galaxy Candidates: Prospects for Catalog and Stacking Searches with IceCube, IceCube-Gen2, and KM3NeT
In high-energy neutrino astrophysics, the identification of high-energy neutrino sources is a central goal, and jet-quiet active galactic nuclei (AGNs) have emerged as promising candidates.Intranight optical monitoring of eight quasars with superluminal jets and low optical polarization: Probing the mechanism of rapid flux variability
Intranight optical variability (INOV) of blazars whose emission arises predominantly from a relativistic jet, has been widely linked to a combination of two key observational diagnostics: the…Feeding or Fleeing: The Impact of Enhanced Early Black Hole Growth on Circumgalactic Clumps at $z > 6$
The circumgalactic medium (CGM) of massive high-redshift galaxies contains inflowing filamentary gas, recycled material, and feedback-driven outflows.
