The Cross-Survey Decade: A Call to Action
Gioia Rau, Robert Benjamin, Federica Bianco +24
By 2027, three flagship wide-field surveys will be operating simultaneously from ground and space, observing overlapping sky and representing more than $6 billion in US and Europea…
Luminosity function of quasars at from SDSS and DESI
Gaocheng Yin, Linhua Jiang, Zhiwei Pan +54
We present a study of the evolution of type 1 quasars at , covering the peak epoch of quasar activity. The quasar evolution has been extensively explored by a variety of…
Stacked Reverberation Mapping of High Redshift Quasars in DESI. I. Feasibility Analysis
Rahma Alfarsy, R. E. A. Canning, Eva-Maria Mueller +49
The broad line region of quasars has long been probed by reverberation mapping techniques that measure time lags between continuum and broad emission line variations. Stacked rever…
Near-infrared emission line diagnostics for AGN from the local Universe to redshift 3
Antonello Calabrò, Laura Pentericci, Anna Feltre +35
Optical rest-frame spectroscopic diagnostics are usually employed to distinguish between star formation and AGN-powered emission. However, this method is biased against dusty sourc…
A comparison between Shapefit compression and Full-Modelling method with PyBird for DESI 2024 and beyond
Y. Lai, C. Howlett, M. Maus +40
DESI aims to provide one of the tightest constraints on cosmological parameters by analysing the clustering of more than thirty million galaxies. However, obtaining such constraint…
Validating the Galaxy and Quasar Catalog-Level Blinding Scheme for the DESI 2024 analysis
U. Andrade, J. Mena-Fernández, H. Awan +60
In the era of precision cosmology, ensuring the integrity of data analysis through blinding techniques is paramount -- a challenge particularly relevant for the Dark Energy Spectro…
