We present the first results from a new survey for high-redshift (z≳ 5) gravitationally lensed
quasars and close quasar pairs. We carry out candidate selection based on the colors and …

The energy released by active galactic nuclei (AGN) has the potential to heat or remove the
gas of the ISM, thus likely impacting the cold molecular gas reservoir of host galaxies at first …

The radio quasar luminosity function exhibits an upturn around W Hz− 1 that is well-
modelled by a star-forming host galaxy population. This distribution leads some authors to …

We present a mock catalog of gravitationally-lensed quasars at z qso< 7.5 with simulated
images for the Rubin Observatory Legacy Survey of Space and Time (LSST). We adopt …

We present a search for galaxy-scale strong gravitational lenses in the initial 2500 square
degrees of the Canada-France Imaging Survey (CFIS). We designed a convolutional neural …

High-redshift binary quasars provide key insights into mergers and quasar activity, and are
useful tools for probing the spatial kinematics and chemistry of galaxies along the line of …

We analyse the star formation (SF) relations in a sample of 16 nearby luminous infrared
galaxies (LIRGs) with more than 2800 regions defined on scales of 90 to 500 pc. We used …

High-redshift dusty star-forming galaxies with very high star formation rates (500− 3000 M⊙
yr− 1) are key to understanding the formation of the most extreme galaxies in the early …

We present a study of the stellar host galaxy, CO (1–0) molecular gas distribution and AGN
emission on 50–500 pc-scales of the gravitationally lensed dust-obscured AGN MG J0751+ …

Feedback from active galactic nuclei (AGN) is thought to be key in shaping the life cycle of
their host galaxies by regulating star-formation activity. Therefore, to understand the impact …
