PIE-ADA: Physics-Informed Ensemble with Adaptive Data Augmentation for Photometric Transient Classification
Deba Priyo Guha, Fariya Tabassum
The upcoming Large Synoptic Survey Telescope (LSST) is expected to observe approximately 10 million astronomical transient events per night, creating an urgent need for automated c…
JAXtronomy: A JAX port of lenstronomy
Alan Huang, Simon Birrer, Daniel Gilman +4
Gravitational lensing is a phenomenon where light bends around massive objects, resulting in distorted images seen by an observer. Studying gravitationally lensed systems provides…
Survey Footprint Explorer: A Browser-Based Interactive Tool for Visualizing and Cross-Matching Astronomical Survey Footprints
S. L. Ahad, R. Brilenkov, J. E. Taylor
We present the Survey Footprint Explorer (v2.5.0), a browser-based interactive tool for visualising and comparing the sky footprints of major astronomical imaging surveys. The tool…
RGC: a radio AGN classifier based on deep learning. I. A semi-supervised multiclass model for VLA images
M. S. Hossain, M. S. H. Shahal, K. M. B. Asad +10
Bent radio active galactic nuclei (RAGNs) -- wide-angle tails (WATs) and narrow-angle tails (NATs) -- trace dense environments in galaxy groups and clusters, yet no multiclass clas…
An accurate measurement of the spectral resolution of the JWST Near Infrared Spectrograph
Anowar J. Shajib, Tommaso Treu, Alejandra Melo +4
The spectral resolution () of spectroscopic data is crucial information for accurate kinematic measurements. In this letter, we present a robust measurement of the…
Morphological Classification of Radio Galaxies using Semi-Supervised Group Equivariant CNNs
Mir Sazzat Hossain, Sugandha Roy, K. M. B. Asad +4
Out of the estimated few trillion galaxies, only around a million have been detected through radio frequencies, and only a tiny fraction, approximately a thousand, have been manual…
Primary beam effects of radio astronomy antennas -- II. Modelling the MeerKAT L-band beam
K. M. B. Asad, J. N. Girard, M. de Villers +12
After a decade of design and construction, South Africa's SKA-MID precursor MeerKAT has begun its science operations. To make full use of the widefield capability of the array, it…
