Zwicky Transient Facility and Globular Clusters: the gr-Band Period-Luminosity Relations for Mira Variables at Maximum Light and Their Applications to Local Galaxies
Chow-Choong Ngeow, Jia-Yu Ou, Anupam Bhardwaj +3
Based on 14 Miras located in 7 globular clusters, we derived the first gr-band period-luminosity (PL) at maximum light for the large-amplitude Mira variables using the multi-year l…

A Distance Measurement to M33 Using Optical Photometry of Mira Variables
Jia-Yu Ou, Chow-Choong Ngeow, Anupam Bhardwaj +4
We present a systematic analysis to determine and improve the pulsation periods of 1637 known long-period Mira variables in M33 using -band light curves spanning ~year…
