Large Magellanic Cloud Globular Clusters in the Near-infrared. I. RR Lyrae in Reticulum
Anupam Bhardwaj, Susmita Das, Prashant Nishad +10
Reticulum is an old, metal-poor, and sparsely populated globular cluster in the outer regions of the Large Magellanic Cloud (LMC) and hosts a rich population of RR Lyrae stars. Bei…
A Pilot Study to Verify the RR Lyrae Candidates with Vera C. Rubin Observatory Early Alerts
Chow-Choong Ngeow, Anupam Bhardwaj, Sarang Shah +2
We present a pilot study using the Vera C. Rubin Observatory early alerts to verify RR Lyrae candidates in the Pan-STARRS1, the Dark Energy Survey, and the Next-Generation Virgo Cl…
Exploring RR Lyrae Variable Stars in the Vera C. Rubin Observatory Data Preview 1
Chow-Choong Ngeow, Anupam Bhardwaj
We investigate the properties of known RR Lyrae in the Vera C. Rubin Observatory Data Preview 1 (DP1) fields and compare those with the predictions based on stellar pulsation model…
Stellar Variability and Distance Indicators in the Near-infrared in Nearby Galaxies. II. Pulsating Stars in the Carina Dwarf Spheroidal
Chow-Choong Ngeow, Anupam Bhardwaj, Prashant Nishad +1
We present homogeneous, near-infrared ( bands) time-series observations of the classical Carina dwarf Spheroidal (dSph) galaxy to determine accurate and precise distances us…
Search for the Optical Counterpart of Einstein Probe Discovered Fast X-ray Transients from Lulin Observatory
Amar Aryan, Ting-Wan Chen, Sheng Yang +24
The launch of the Einstein Probe (EP) mission has revolutionized the detection and follow-up observations of fast X-ray transients (FXTs) by providing prompt and timely access to t…
Commissioning of a Commercial CMOS Camera for the Application of Lucky Image Technique on the Lulin One-meter Telescope
Yang-Peng Hsieh, Chow-Choong Ngeow
Lucky image (LI) is a technique to achieve near diffraction-limit high-angular resolution images for meter-class optical telescopes. In this work, by observing the core of globular…
