Integral Field Spectroscopy of the Cometary Starburst Galaxy NGC 4861

Nathan Roche, José M. Vílchez, Jorge Iglesias-Páramo +4

Using the PMAS Integral Field Unit on the Calar Alto 3.5m telescope we observed the southern component (Markarian 59) of the `cometary' starburst galaxy NGC 4861. Mrk 59 is centred…

MUSE 3D Spectroscopy and Kinematics of the gigahertz peaked spectrum Radio Galaxy PKS 1934-63: Interaction, Recently Triggered AGN and Star Formation

Nathan Roche, Andrew Humphrey, Patricio Lagos +4

We observe the radio galaxy PKS 1934-63 (at ) using MUSE (Multi Unit Spectroscopic Explorer) on the Very Large Telescope (VLT). The radio source is GigaHertz Peaked Spect…

CALIFA Spectroscopy of the Interacting Galaxy NGC 5394 (Arp 84): Starbursts, Enhanced [NII]6584 and Signs of Outflows and Shocks

Nathan Roche, Andrew Humphrey, Jean Michel Gomes +3

We investigate the spiral galaxy NGC 5394, which is strongly interacting with the larger spiral NGC 5395 (the pair is Arp 84), using optical integral-field spectroscopy from the CA…

Witnessing the transformation of a quasar host galaxy at z=1.6

A. Humphrey, N. Roche, J. M. Gomes +9

A significant minority of high redshift radio galaxy (HzRG) candidates show extremely red broad band colours and remain undetected in emission lines after optical `discovery' spect…

Spectroscopy of 7 Radio-Loud QSOs at 2<z<6: Giant Lyman-alpha Nebulae Accreting onto Host Galaxies

Nathan Roche, Andrew Humphrey, Luc Binette

We performed long-slit optical spectroscopy (GTC-OSIRIS) of 6 radio-loud QSOs at redshifts , known to have giant (-100 kpc) Lyman- emitting nebulae, and detect e…
