Mapping Distortion of Detectors in UVIT Onboard AstroSat Observatory
V. Girish, Shyam N. Tandon, S. Sriram +2
Ultraviolet Imaging Telescope (UVIT) is one of the payloads onboard AstroSat, India's first multi-wavelength Astronomy mission. UVIT is primarily designed to make high resolution i…
Monitoring Microtubule Mechanical Vibrations via Optomechanical Coupling
Sh. Barzanjeh, V. Salari, J. A. Tuszynski +2
The possible disruption of a microtubule during mitosis can control the duplication of a cancer cell. Cancer detection and treatment may be possible based on the detection and cont…
An analysis of star formation with Herschel in the Hi-GAL Survey. II. The tips of the Galactic bar
M. Veneziani, E. Schisano, D. Elia +20
We present the physical and evolutionary properties of prestellar and protostellar clumps in the Herschel Infrared GALactic plane survey (Hi-GAL) in two large areas centered in the…
A Hot Companion to a Blue Straggler in NGC188 as Revealed by the Ultra-violet Imaging Telescope (UVIT) on ASTROSAT
Subramaniam Annapurni, Sindhu N., Tandon S. N. +14
We present early results from the Ultra-Violet Imaging Telescope (UVIT) onboard the ASTROSAT observatory. We report the discovery of a hot companion associated with one of the blue…
In-orbit Performance of UVIT and First Results
S. N. Tandon, J. B. Hutchings, S. K. Ghosh +23
The performance of the ultraviolet telescope (UVIT) on-board ASTROSAT is reported. The performance in orbit is also compared with estimates made from the calibrations done on the g…
Geometry of Hessenberg varieties with applications to Newton-Okounkov bodies
Hiraku Abe, Lauren DeDieu, Federico Galetto +1
In this paper, we study the geometry of various Hessenberg varieties in type A, as well as families thereof, with the additional goal of laying the groundwork for future computatio…
