Euclid preparation XXX. Performance assessment of the NISP red grism through spectroscopic simulations for the wide and deep surveys
Frédéric Courbin, Georges Meylan, Gianluca Castignani, Maurizio Martinelli, Yi Wang, Richard Massey, Fabio Finelli, Marcello Farina
This work focusses on the pilot run of a simulation campaign aimed at investigating the spectroscopic capabilities of the Euclid NearInfrared Spectrometer and Photometer (NISP), in terms of continuum and emission line detection in the context of galaxy evo ...
EDP SCIENCES S A2023A novel hydrogenic spectroscopic technique for inferring the role of plasma-molecule interaction on power and particle balance during detached conditions
Basil Duval, Artur Perek, Kevin Henricus Annemarie Verhaegh, Mirko Wensing
Detachment, an important mechanism for reducing target heat deposition, is achieved through reductions in power, particle and momentum; which are induced through plasma-atom and plasma-molecule interactions. Experimental research in how those reactions pre ...
IOP PUBLISHING LTD2021A study of the influence of plasma-molecule interactions on particle balance during detachment
Basil Duval, Christian Gabriel Theiler, Artur Perek, Kevin Henricus Annemarie Verhaegh, Mirko Wensing
In this work we provide experimental insights into the impact of plasma-molecule interactions on the target ion flux decrease during divertor detachment achieved through a core density ramp in the TCV tokamak. Our improved analysis of the hydrogen Balmer s ...
ELSEVIER2021Atomic data for the
Context. We describe the atomic and molecular data that were used for the abundance analyses of FGK-type stars carried out within the Gaia-ESO Public Spectroscopic Survey in the years 2012 to 2019. The Gaia-ESO Survey is one among several current and futur ...
EDP SCIENCES S A2021Quasi-stellar objects acting as potential strong gravitational lenses in the SDSS-III BOSS survey
Jean-Paul Richard Kneib, Frédéric Courbin, Timothée Guy Olivier Delubac
We present a sample of 12 quasi-stellar objects (QSOs) that potentially act as strong gravitational lenses on background emission line galaxies (ELG) or Lyman-alpha emitters (LAEs) selected through a systematic search of the 297 301 QSOs in the Sloan Digit ...
EDP SCIENCES S A2019Observation of the 1S-2P Lyman-alpha transition in antihydrogen
In 1906, Theodore Lyman discovered his eponymous series of transitions in the extreme-ultraviolet region of the atomic hydrogen spectrum(1,2). The patterns in the hydrogen spectrum helped to establish the emerging theory of quantum mechanics, which we now ...
Nature Publishing Group2018Spectroscopic investigations of divertor detachment in TCV
Basil Duval, Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Umar Sheikh, Nicola Vianello, Federico Nespoli, Cedric Kar-Wai Tsui, Kevin Henricus Annemarie Verhaegh, Wouter Vijvers, Roberto Maurizio, Claudio Marini
The aim of this work is to provide an understanding of detachment at TCV with emphasis on analysis of the Balmer line emission. A new Divertor Spectroscopy System has been developed for this purpose. Further development of Balmer line analysis techniques h ...
2017Understanding the interplay between the solvent and nuclear rearrangements in the negative solvatochromism of a push-pull flexible quinolinium cation
A detailed computational characterization of the one-photon absorption spectrum of a 2-((E)-2-[ 2,2']-bithiophenyl-5-yl-vinyl)-1-methyl-quinolinium cation in acetonitrile solution is presented. The main physico-chemical effects (solvation, vibronic progres ...
Royal Soc Chemistry2017The Gaia-ESO Survey: dynamics of ionized and neutral gas in the Lagoon nebula (M 8)
Aims. We present a spectroscopic study of the dynamics of the ionized and neutral gas throughout the Lagoon nebula (M 8), using VLT-FLAMES data from the Gaia-ESO Survey. The new data permit exploration of the physical connections between the nebular gas an ...
Edp Sciences S A2017NEAR-ULTRAVIOLET SPECTROSCOPY OF STAR-FORMING GALAXIES FROM eBOSS: SIGNATURES OF UBIQUITOUS GALACTIC-SCALE OUTFLOWS
Jean-Paul Richard Kneib, Johan Comparat, Anand Stéphane Raichoor, Jeffrey Newman, Timothée Guy Olivier Delubac
We present rest-frame near-ultraviolet (NUV) spectroscopy of star-forming galaxies (SFGs) at 0.6 < z < 1.2 from the Extended Baryon Oscillation Spectroscopic Survey (eBOSS) in SDSS-IV. One of the eBOSS programs is to obtain 2 ''. (about 15 kpc) fiber spect ...
