Theoretical Pulsation Properties of RR Lyrae and Type II Cepheids in the JWST and Roman photometric systems
RR Lyrae (RRL) stars and Type II Cepheids (T2Cs) are key standard candles and tracers of old stellar populations.Multiphase Gas Structure in JWST Little Red Dots
JWST has uncovered a population of compact high-redshift galaxies, 'little red dots' (LRDs), exhibiting broad Balmer emission lines that often show narrow absorption features and strong Balmer…Partial Fragmentation of Comet C/2025 K1 (ATLAS)
We present time-series observations of the long period comet C/2025 K1 (ATLAS) obtained in 2025-2026, bracketing the comet's fragmentation in early November 2025.O VI Emission in Starbursting BCGs: An HST-COS Extension of "Reigniting the FUSE"
In this extension of our "Reigniting the FUSE" series, we have obtained new far-ultraviolet spectroscopy of 3 starbursting brightest cluster galaxies with the Cosmic Origins Spectrograph (COS)…Late Epoch Infrared Spectroscopy and Two-Component 3D Photoionization Modeling of Classical Nova V5668 Sgr
V5668 Sgr is an Fe II classical nova (CN) that exploded on 15 March 2015.Catastrophe Structure and Stability of Axion Stars
Axion stars are self-gravitating Bose--Einstein condensates of QCD axions or axion-like particles.Emission line stacking on cosmological scales: equivalence to two-point statistics and modelling of the observational effects
Emission line stacking measurement for cosmological line intensity mapping (LIM) contains not only the average emission line profile of the stacked sources, but usually also the clustering signal…Effects of Synchrotron Self-Absorption on Polarization Diagnostics of MHD Turbulence
Synchrotron polarization is a powerful tool for diagnosing magnetohydrodynamic (MHD) turbulence, yet prior analyses are confined to the optically thin regime, neglecting the effects of synchrotron…On the Evolution of Circumstellar Disks Modified by the Presence of a Binary
Stars form within circumstellar disks, and some binary stars develop circumbinary disks surrounding the pair.SMMAN Studies of AGN Variability. I. Long-term Spectral Evolution and a Candidate $\sim1000$-day Quasi-periodic Modulation in 4C+72.28
The SMMAN project has carried out nine years of radio flux monitoring in the C and K bands of the blazar 4C+72.28.Galaxy Luminosity Functions at z~7-10 from Four Years of JWST Observations
We present galaxy luminosity functions at $z\approx 7.4$ and 10 based on a comprehensive search for candidate galaxies at $6.4\lesssim z\lesssim11.3$ in JWST's public NIRCam data four years after…Differential and integral scaling laws of the mass density of molecular clouds
In this work we investigate the mass density - size scaling law in molecular clouds (MCs).Binary Dynamics and Mergers in a Stellar Disk and the Formation of Dusty Objects in the Galactic Center
For more than a decade, observers have been tracking a population of enigmatic dusty objects orbiting the central supermassive black hole of the Milky Way, Sagittarius A$^\star$ (SgrA$^\star$).Local Analogs of Little Red Dots: Clues to the X-ray Weakness
A major question about JWST's little red dots (LRDs) at $z\sim4-8$ is the origin of their apparent X-ray weakness.Star clusters at cosmic dawn I: the emergence of the initial cluster mass function
JWST observations of lensed galaxies reveal unusually bright star-cluster candidates within the first billion years after the Big Bang.The Galactic rotation curve from the ALS III catalogue of OB Stars
The Galactic rotation curve reveals the radial mass distribution of the Milky Way, but its determination depends on the tracer population.Forward model of the Gaia DR3 selection function
The completeness of an astronomical catalogue depends on its selection function, which is a combination of the observing strategy, instrumental characteristics, and intrinsic properties of the…Polarization Observations of NGC 315 with FAST
We present new continuum and polarization observations of radio galaxy NGC 315 obtained with the Five-hundred-meter Aperture Spherical radio Telescope (FAST) over 1.0-1.5 GHz.Spatial distribution of star formation in dwarf galaxies: Merger-driven and secular starburst
Galaxy interactions can induce bursts of star formation (SF), while internal or secular processes can also trigger starbursts (SB).Magnetic Reconnection Modifies Cosmic-Ray Transport in the Interstellar Medium
We present numerical magnetohydrodynamic (MHD) simulations of the interstellar medium in gravity-stratified boxes with the Piernik MHD code.
