A Search For Stellar-mass Black Holes Via Astrometric Microlensing II: 2012-2015 Keck Candidates
Mace J. Huston, Jessica R. Lu, Casey Y. Lam +58
The Milky Way is expected to host 10 stellar-mass black holes with an uncertain binary fraction. The only proven method to detect isolated stellar mass black holes is gra…
Zwicky Transient Facility and Globular Clusters: The Period-Luminosity and Period-Wesenheit Relations for Type II Cepheids
Chow-Choong Ngeow, Anupam Bhardwaj, Jing-Yi Henderson +5
We present the first gri-band period-luminosity (PL) and period-Wesenheit (PW) relations for 37 Type II Cepheids (hereafter TIIC) located in 18 globular clusters based on photometr…
Zwicky Transient Facility and Globular Clusters: The RR Lyrae gri-Band Period-Luminosity-Metallicity and Period-Wesenheit-Metallicity Relations
Chow-Choong Ngeow, Anupam Bhardwaj, Richard Dekany +7
Based on time-series observations collected from Zwicky Transient Facility (ZTF), we derived period-luminosity-metallicity (PLZ) and period-Wesenheit-metallicity (PWZ) relations fo…
Zwicky Transient Facility and Globular Clusters: the Period-Luminosity and Period-Luminosity-Color Relations for Late-Type Contact Binaries
Chow-Choong Ngeow, Szu-Han Liao, Eric C. Bellm +7
In this work, we aimed to derive the -band period-luminosity (PL) and period-luminosity-color (PLC) relations for late-type contact binaries, for the first time, located in th…
Gravitational Microlensing Event Statistics for the Zwicky Transient Facility
Michael S. Medford, Jessica R. Lu, William A. Dawson +4
Microlensing surveys have discovered thousands of events with almost all events discovered within the Galactic bulge or toward the Magellanic clouds. The Zwicky Transient Facility…
