The nuclear activity and central structure of the elliptical galaxy NGC 5322
Bililign T. Dullo, Johan H. Knapen, David R. A. Williams +7
We have analysed a new high-resolution e-MERLIN 1.5 GHz radio continuum map together with and SDSS imaging of NGC 5322, an elliptical galaxy hosting radio jets, aiming to und…
A remarkably large depleted core in the Abell 2029 BCG IC 1101
Bililign T. Dullo, Alister W. Graham, Johan H. Knapen
We report the discovery of an extremely large (R_b ~ 2"77 ~ 4.2 kpc) core in the brightest cluster galaxy, IC 1101, of the rich galaxy cluster Abell 2029. Luminous core-Sérsic gala…
Too big to be real? No depleted core in Holm 15A
Paolo Bonfini, Bililign T. Dullo, Alister W. Graham
Partially depleted cores, as measured by core-Sersic model "break radii", are typically tens to a few hundred parsecs in size. Here we investigate the unusually large (cusp radius…
Hiding in plain sight: An abundance of compact massive spheroids in the local Universe
Alister W. Graham, Bililign T. Dullo, Giulia A. D. Savorgnan
It has been widely remarked that compact, massive, elliptical-like galaxies are abundant at high redshifts but exceedingly rare in the Universe today, implying significant evolutio…
