Unveiling large-scale rotational motions in the intragroup medium at z~1 through gravitational-arc tomography
Cédric Ledoux, Fernanda Muñoz-Olivares, L. Felipe Barrientos +8
We present the first spatially resolved characterisation of the cool intragroup medium (IGrM) in a spectroscopically confirmed galaxy group at z=1.167. Using 30 independent sightli…
A z1 galactic-scale outflow transversally mapped to 50 kpc through gravitational-arc tomography
J. A. Hernández-Guajardo, L. F. Barrientos, S. López +12
We report spatially resolved measurements of cool gas traced by Mg II and Fe II absorption in the circumgalactic medium (CGM) of a star-forming galaxy at (G1). The fortuit…
One H2 molecule per ten million H-atoms reveals sub-pc scale cold overdensities at z~4
P. Noterdaeme, S. Balashev, T. Berg +11
We present the detection and analysis of H2 absorption at z = 4.24 towards the bright quasar J0007-5705, observed with the Very Large Telescope as part of the ESPRESSO QUasar Absor…
Automated quasar continuum estimation using neural networks: a comparative study of deep-learning architectures
Francesco Pistis, Michele Fumagalli, Matteo Fossati +13
Context. Ongoing and upcoming large spectroscopic surveys are drastically increasing the number of observed quasar spectra, requiring the development of fast and accurate automated…
First results on RR Lyrae stars with the TESS space telescope: untangling the connections between mode content, colors and distances
László Molnár, Attila Bódi, András Pál +25
The TESS space telescope is collecting continuous, high-precision optical photometry of stars throughout the sky, including thousands of RR Lyrae stars. In this paper, we present r…
Four 'Peculiar' RRd Stars Observed by K2
James M. Nemec, Pawel Moskalik
Four stars pulsating simultaneously with a dominant period (0.28,0.39) d and an {\it additional} period (0.20,0.27) d have been identified from among the more t…
