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…
The nature of ASASSN-24fw's occultation: modelling the event as dimming by optically thick rings around a sub-stellar companion
Sarang Shah, Jonathan P. Marshall, Carlos del Burgo +12
ASASSN-24fw is a main-sequence F-type star that experienced a rapid and long-lasting dimming event beginning in late 2024 and continuing until mid 2025. Its pre-dimming spectral en…
A Dynamic, Signals-Based Reinterpretation of Microeconomic Theory
Sarang Shah
Economics has long been a science of static equilibria, in which time is a second-order rather than first-order concern. Without time, economic modelers may neglect or obscure the…
Moduli Space of SU(2) Singular Monopole
Sarang Shah
The monopole with a Dirac singularity was constructed in Durcan (2007) and Cherkis and Durcan (2007). We study its moduli space by identifying the tangent direction to the…
