Fundamental differences in the properties of red and blue quasars: measuring the reddening and accretion properties with X-shooter (2022)
Journal Article

We have recently found fundamental differences in the radio properties of red quasars when compared to typical blue quasars. In this paper, we use data from the X-shooter spectrograph on the Very Large Telescope, providing spectral coverage from ∼300...

Host Dark Matter Halos of SDSS Red and Blue Quasars: No Significant Difference in Large-scale Environment (2022)
Journal Article

The observed optical colors of quasars are generally interpreted in one of two frameworks: unified models that attribute the color to the random orientation of the accretion disk along the line of sight, and evolutionary models that invoke connection...

How Are Red and Blue Quasars Different? The Radio Properties (2021)
Journal Article

A non-negligible fraction of quasars are red at optical wavelengths, indicating (in the majority of cases) that the accretion disc is obscured by a column of dust which extinguishes the shorter-wavelength blue emission. In this paper, we summarize re... Read More about How Are Red and Blue Quasars Different? The Radio Properties.

Fundamental differences in the radio properties of red and blue quasars: kiloparsec-scale structures revealed by e-MERLIN (2021)
Journal Article

Red quasi-stellar objects (QSOs) are a subset of the quasar population with colours consistent with reddening due to intervening dust. Recent work has demonstrated that red QSOs show special radio properties that fundamentally distinguish them from n...

The multiwavelength properties of red QSOs -- Evidence for dusty winds as the origin of QSO reddening (2021)
Journal Article

Fundamental differences in the radio properties of red quasars (QSOs), as compared to blue QSOs, have been recently discovered, positioning them as a potential key population in the evolution of galaxies and black holes across cosmic time. To elucida... Read More about The multiwavelength properties of red QSOs -- Evidence for dusty winds as the origin of QSO reddening.

Fundamental differences in the radio properties of red and blue quasars: enhanced compact AGN emission in red quasars (2020)
Journal Article

We have recently used the Faint Images of the Radio Sky at Twenty-centimeters (FIRST) survey to show that red quasars have fundamentally different radio properties to typical blue quasars: a significant (factor ≈3) enhancement in the radio-detection... Read More about Fundamental differences in the radio properties of red and blue quasars: enhanced compact AGN emission in red quasars.

Fundamental differences in the radio properties of red and blue quasars: Insight from the LOFAR Two-metre Sky Survey (LoTSS) (2020)
Journal Article

Red quasi-stellar objects (QSOs) are a subset of the luminous end of the cosmic population of active galactic nuclei (AGN), most of which are reddened by intervening dust along the line-of-sight towards their central engines. In recent work from our... Read More about Fundamental differences in the radio properties of red and blue quasars: Insight from the LOFAR Two-metre Sky Survey (LoTSS).

Fundamental differences in the radio properties of red and blue quasars: evolution strongly favoured over orientation (2019)
Journal Article

A minority of the optically selected quasar population are red at optical wavelengths due to the presence of dust along the line of sight. A key focus of many red quasar studies is to understand their relationship with the overall quasar population:...
