Rogue Ones: Orbital census of Galactic Cepheids and their Anomalies

Shourya Khanna, Ronald Drimmel, Eloisa Poggio +2

Classical Cepheids (DCEPs) are excellent standard candles expected to trace the spatial and kinematic distribution of the Galaxy's young and dynamically cold stellar disc. Using th…

The Effect of a Non-universal Extinction Curve on the Wesenheit Function and Cepheid Distances

D. M. Skowron, M. L. Fouesneau, R. Drimmel +1

The Wesenheit function is widely used to reduce the effects of interstellar reddening in distance measurements. Its construction, however, relies on the assumption of a universal e…

Microlensing optical depth, event rate, and limits on compact objects in dark matter based on 20 yr of OGLE observations of the Small Magellanic Cloud

P. Mróz, A. Udalski, M. K. Szymański +12

Some previous studies have suggested that massive and intermediate-mass primordial black holes (PBHs) could comprise a substantial fraction of dark matter in the Universe. Such bla…

The Milky Way as Seen by Classical Cepheids II: Spiral Structure

Ronald Drimmel, Shourya Khanna, Eloisa Poggio +1

As a relatively young and bright population and the archetype of standard candles, classical Cepheids are an ideal population on which to trace the non-axisymmetric structure in th…

The Milky Way as Seen by Classical Cepheids I: Distances Based on Mid-infrared Photometry

Dorota M. Skowron, Ronald Drimmel, Shourya Khanna +3

Classical Cepheids are the archetype of the standard candle, thanks to the period-luminosity relation which allows to measure their intrinsic brightness. They are also relatively y…

Virial Black Hole Masses for AGNs behind the Magellanic Clouds

Swayamtrupta Panda, Szymon Kozłowski, Mariusz Gromadzki +13

We use the spectroscopic data collected by the Magellanic Quasars Survey (MQS) as well as the photometric V- and I-band data from the Optical Gravitational Lensing Experiment (OGLE…
