Research of signs of star formation in three S0 galaxies - members of isolated pairs
We obtained and analyzed long-slit spectra of three lenticular galaxies with optical rings: PGC 48114, ESO 234-011, and ESO 444-076.The Physics of the Cold and Warm Interstellar Medium Through Radio Recombination Lines
The interplay between star formation and the interstellar medium (ISM) gives rise to a feedback cycle that is one of the key drivers of galaxy evolution.Physics Informed Neural Network for Multi-dimensional Turbulent Self-gravitating Flows
Molecular clouds exhibit complex, multi-scale dynamics driven by the interplay of turbulence, self-gravity, and gas pressure.Complete Multi-Band Structural Characterization for 10 Million Galaxies in the Hyper Suprime-Cam Wide Survey using Deep Learning
Galaxy structure is wavelength-dependent, as different photometric bands trace distinct stellar populations and structural components.A Population Synthesis Model for Odd Radio Circles Produced by Shock-Bubble Interactions
Odd Radio Circles (ORCs) are edge-brightened rings of diffuse radio emission of roughly arcminute size whose physical origin remains debated.One-Million-Year-Old Nascent Eclipsing Binaries in the LMC
The light curves of nascent eclipsing binaries (EBs) feature sinusoidal reflection effects as a hot B-type main-sequence (MS) primary irradiates the near side of a cool, low-mass, pre-MS companion.A probabilistic approach to separate mergers and jellyfish galaxies: Application of morphological non-parametric indexes to the DESI Legacy Survey
Galaxy morphology traces the physical processes that shape galaxy evolution, but non-parametric diagnostic boundaries depend on image quality and preprocessing.Comprehensive Visible and Near-infrared Keck and Gemini Monitoring and Characterization of Interstellar Comet 3I/ATLAS during its Encounter with the Solar System
We present 14 optical imaging and eight optical spectroscopic epochs of interstellar comet 3I/ATLAS from Keck/LRIS and Gemini/GMOS, two near-infrared (NIR) imaging epochs from Keck/MOSFIRE, and four…A Composite Rest-Frame UV Spectrum of Galaxies at $5.7 < z < 6.9$: Ionization, Outflows, and Implications for Intergalactic Metal Enrichment
We present a stacked JWST/NIRSpec spectrum of 104 galaxies at $λ_{\rm rest}=1200\unicode{x2013}2000\;\mathrm{\mathring{A}}$ to study nebular emission and absorption from the interstellar medium…$El\ Ascua$: An ultra-luminous, radio-loud, Compton-thick AGN at $z\sim 3.8$ hiding in plain sight revealed by MINERVA multi-band MIRI observations
Heavily dust-obscured active galactic nuclei (AGN) are crucial for understanding supermassive black hole growth.Dark Matter and MOND successes and degeneracies in reproducing SPARC rotation curves and weak lensing data
The observed rotation velocities of spiral galaxies at large scales exceed those predicted by their baryonic components, motivating the need for dark matter (DM) or Modified Newtonian Dynamics (MOND).Assessing the detectability of a realistic massive black hole binary population in LSST
Electromagnetic signatures of massive black hole binaries (MBHB) are expected to be found in quasar light curves.SN Ares: A Strongly Lensed Type IIb Supernova at $\mathbf{z=1.276}$ with a Predicted 70-Year Time Delay
We present the discovery of supernova (SN) Ares, a strongly lensed supernova at $z_{\rm spec}=1.276\pm0.002$ in a massive, triply imaged host galaxy behind the MACS J0308.9+2645 galaxy cluster.The Hosts and Mass Distribution Function of the Most Massive Black Holes: Implications for the nHz Gravitational Wave Background
We use the core-radius, $r_γ,$ of a galaxy's central core along with a volume-limited sample of brightest cluster galaxies (BCG) to determine the $z=0$ mass distribution function of the most massive…How Steep is your Dust? Direct Measurements of Nebular Attenuation Curves at Cosmic Noon with JWST
Tracing the shape of the nebular attenuation curve, which is crucial for accurately measuring intrinsic emission-line fluxes, has proven challenging both in the local universe and at high redshift.Recently launched AGN-driven outflow in a lensed quiescent galaxy at Cosmic Noon
We analyze JWST/NIRSpec IFU spectroscopy of MRG-M0150, a gravitationally lensed, massive quiescent galaxy at $z=2.6$ from the INQUEST-JWST survey.Initial Conditions of Magnetized AGN Accretion Disks from Cloud Capture and Disruption
Accretion onto supermassive black holes (BHs) from the ISM can occur via capture of cold gas 'clouds' (GMCs, clumps, or overdense structures).Exploring the UV Fe III Emission along the Quasar Main Sequence
The diversity of Type I AGNs can be organized along the Quasar Main Sequence (MS), a powerful framework primarily driven by the accretion rate and defined in the optical plane by the FWHM of…The SIRMOS mission concept: a space-based near-IR spectroscopic survey of 100 million galaxies in the Euclid Wide Survey footprint
SIRMOS is a mission concept for a future NASA Astrophysics Explorer opportunity that aims to revolutionize our understanding of the universe by mapping the large-scale structure of galaxies in…Rest-frame Ultraviolet Variability of Quasars in the Cosmic Himalayas Overdensity
Some high-redshift overdensities show an enhanced incidence of AGNs, suggesting that large-scale environment may influence supermassive black hole fuelling and triggering.
