WST instrument Exposure Time Calculator: full simulation of multi-mode spectrograph performance from source to detector
Matteo Ferro, Matteo Genoni, Henri M. J. Boffin +13
We present a comprehensive Exposure Time Calculator (ETC) developed for the Wide-field Spectroscopic Telescope (WST) concept. The WST, currently in its conceptual phase, is designe…
A pilot sample of Planck-selected strongly lensed sub-mm galaxies: NOEMA observations and physical characterisation
Leonardo Trobbiani, Matteo Bonato, Ivano Baronchelli +6
The extreme brightness of high- strongly lensed galaxies detected by Planck surveys, thanks to their exceptionally large gravitational magnifications, offers a unique opportunit…
No evolution in the number density of little red dots from cosmic dawn to cosmic noon
Federica Loiacono, Roberto Gilli, Marco Mignoli +24
We present our search for little red dots (LRDs) in the "J1030 field", a region of the sky around the quasar SDSS J1030+0524, observed by the JWST EIGER program. Over 1…
Little Red and Blue Dots: AGN-excited narrow lines, Lyman- emission, and resemblance to standard quasars
Sophia Geris, Roberto Maiolino, Xihan Ji +35
We present an analysis of a sample of 36 Little Red and Blue Dots (LRDs and LBDs) at , identified by JWST in the GOODS fields. While both categories are selected to ha…
Beyond the Dot: an LRD-like nucleus at the Heart of an IR-Bright Galaxy and its implications for high-redshift LRDs
Pierluigi Rinaldi, George H. Rieke, Zihao Wu +23
Little Red Dots (LRDs) are compact, red sources discovered by JWST at high redshift (), marked by distinctive 'V-shaped' spectral energy distributions (SEDs) and often…
The WISSHFUL program: the highest redshift UFO discovered in a non-lensed QSO
G. Lanzuisi, L. Borrelli, E. Piconcelli +28
We present the first results from the WISSHFUL program, an XMM-Newton heritage program targeting luminous QSOs at Cosmic Noon. We report on recent simultaneous XMM-Newton and NuSTA…
