      Similarly to the cosmic star formation history, the black hole accretion rate density of the Universe peaked at 1<$z$<3. This cosmic epoch is hence best suited for investigating the effects of radiative feedback from active ...

      A decade of surveys has hinted at a possible higher occurrence rate of debris discs in systems hosting low mass planets. This could be due to common favourable forming conditions for rocky planets close in and planetesimals ...
    • ALMA observations of the η Corvi debris disc: Inward scattering of CO-rich exocomets by a chain of 3-30 M⊕ planets? 

      Marino, Sebastian; Wyatt, Mark Charles; Panić, O; Matrà, Luca; Kennedy, Grant Malcolm; Bonsor, Amy Hannah; Kral, Q et al. (Oxford University Press, 2017-01-01)
      While most of the known debris discs present cold dust at tens of astronomical unit (au), a few young systems exhibit hot dust analogous to the Zodiacal dust. η Corvi is particularly interesting as it is old and it has ...
