Collisional removal of H I from the inner disks of Virgo Cluster galaxies
Monica Valluri,Chanda J. Jog +1 more
TL;DR: In this paper, it is shown that collisions between galaxies in a cluster can lead to the removal of H I gas from these galaxies while leaving the H 2 gas, undisturbed.
A Cepheid-Based Distance to the Seyfert Galaxy NGC 6814
Misty C. Bentz,Laura Ferrarese,Christopher A. Onken,Bradley M. Peterson,Bradley M. Peterson,Monica Valluri +5 more
TL;DR: In this article, the authors presented a Cepheid-based distance to the nearby Seyfert galaxy NGC\,6814 from NASA's Hubble Space Telescope observations, where they obtained F555W and F814W imaging over the course of 12 visits with logarithmic time spacing in 2013 August-October.
Schwarzschild modeling of barred galaxies
Eugene Vasiliev,Monica Valluri +1 more
TL;DR: In this article, the Schwarzschild orbit-superposition approach is used to deal with a large class of systems, including rotating barred disk galaxies, and the intrinsic degeneracy of determining the potential from line-of-sight kinematics is discussed.
The shape of the dark matter halo revealed from a hypervelocity star
Kohei Hattori,Monica Valluri +1 more
- 01 Jun 2019
TL;DR: In this paper, the authors estimate the flattening of the Galactic dark matter halo by using the Gaia DR2 data and the circular velocity data and show that the orbit of J01020100-7122208 favors a prolate halo within 10 kpc from the Galactic center.
Difficulties with Recovering the Masses of Supermassive Black Holes from Stellar Kinematical Data
TL;DR: In this article, the authors show that the potential estimation problem is generically underdetermined when applied to long-slit kinematical data of the kind used for most black hole mass determinations to date.
