The upcoming 4m ILMT facility and data reduction pipeline testing
Brajesh Kumar, Vibhore Negi, Bhavya Ailawadhi +5
The 4m International Liquid Mirror Telescope (ILMT) installation activities have recently been completed at the Devasthal observatory (Uttarakhand, India). The ILMT will perform co…
Search for an alien communication from the Solar System to a neighbor star
Michael Gillon, Artem Burdanov, Jason T. Wright
Under the hypothesis that self-reproducing probes have formed a galactic-scale communication network by direct Gravitationally-Lensed (GL) links between neighboring systems, we ide…
Ultraviolet Spectropolarimetry: on the origin of rapidly rotating B stars
C. E. Jones, J. Labadie-Bartz, D. V. Cotton +12
UV spectroscopy and spectropolarimetry hold the key to understanding certain aspects of massive stars that are largely inaccessible with optical or longer wavelength observations.…
Auto-RSM: an automated parameter-selection algorithm for the RSM map exoplanet detection algorithm
Carl-Henrik Dahlqvist, Faustine Cantalloube, Olivier Absil
Most of the high-contrast imaging (HCI) data-processing techniques used over the last 15 years have relied on the angular differential imaging (ADI) observing strategy, along with…
Focal Plane Wavefront Sensing using Machine Learning: Performance of Convolutional Neural Networks compared to Fundamental Limits
G. Orban de Xivry, M. Quesnel, P. -O. Vanberg +2
Focal plane wavefront sensing (FPWFS) is appealing for several reasons. Notably, it offers high sensitivity and does not suffer from non-common path aberrations (NCPA). The price t…
The vector-apodizing phase plate coronagraph: design, current performance, and future development
D. S. Doelman, F. Snik, E. H. Por +50
Over the last decade, the vector-apodizing phase plate (vAPP) coronagraph has been developed from concept to on-sky application in many high-contrast imaging systems on 8-m class t…
