Supervised detection of exoplanets in high-contrast imaging sequences
Carlos Alberto Gomez Gonzalez, Olivier Absil, Marc van Droogenbroeck
Post-processing algorithms play a key role in pushing the detection limits of high-contrast imaging (HCI) instruments. State-of-the-art image processing approaches for HCI enable t…
An H-band Vector Vortex Coronagraph for the Subaru Coronagraphic Extreme-Adaptive Optics System
Jonas Kühn, Eugene Serabyn, Julien Lozi +11
The vector vortex is a coronagraphic imaging mode of the recently commissioned Subaru Coronagraphic Extreme-Adaptive Optics (SCExAO) platform on the 8-m Subaru Telescope. This mult…
A New Standard for Assessing the Performance of High Contrast Imaging Systems
Rebecca Jensen-Clem, Dimitri Mawet, Carlos A. Gomez Gonzalez +8
As planning for the next generation of high contrast imaging instruments (e.g. WFIRST, HabEx, and LUVOIR, TMT-PFI, EELT-EPICS) matures, and second-generation ground-based extreme a…
SPECULOOS exoplanet search and its prototype on TRAPPIST
Artem Burdanov, Laetitia Delrez, Michaël Gillon +1
One of the most significant goals of modern science is establishing whether life exists around other suns. The most direct path towards its achievement is the detection and atmosph…
Redshift determination through weighted phase correlation: a linearithmic implementation
L. Delchambre
We present a new algorithm having a time complexity of O(N log N) and designed to retrieve the phase at which an input signal and a set of not necessarily orthogonal templates matc…
K-shell photoabsorption and photoionization of trace elements. II. Isoelectronic sequences with electron number
C. Mendoza, M. A. Bautista, P. Palmeri +3
We are concerned with improving the diagnostic potential of the K lines and edges of elements with low cosmic abundances that are observed in the X-ray spectra of supernova remnant…
