[NII] fine-structure emission at 122 and 205um in a galaxy at z=2.6: a globally dense star-forming interstellar medium
M. J. Doherty, J. E. Geach, R. J. Ivison +1
We present new observations with the Atacama Large Millimeter/sub-millimeter Array of the 122um and 205um fine-structure line emission of singly-ionised nitrogen in a strongly lens…
Optical and near-IR spectroscopy of candidate red galaxies in two z~2.5 proto-clusters
Michelle Doherty, Masayuki Tanaka, Carlos De Breuck +9
We present a spectroscopic campaign to follow-up red colour-selected candidate massive galaxies in two high redshift proto-clusters surrounding radio galaxies. We observed a total…
The edge of the M87 halo and the kinematics of the diffuse light in the Virgo cluster core
Michelle Doherty, Magda Arnaboldi, Payel Das +7
We present high resolution FLAMES/VLT spectroscopy of intracluster planetary nebula (ICPN) candidates, targeting three new fields in the Virgo cluster core with surface brightness…
Expansion velocities and core masses of bright planetary nebulae in the Virgo cluster
Magda Arnaboldi, Michelle Doherty, Ortwin Gerhard +5
The line-of-sight velocities and [OIII] 5007 AA expansion velocities are measured for 11 planetary nebulae (PNs) in the Virgo cluster core, at 15 Mpc distance, with the FLAMES spec…
The star formation rate at redshift one: H-alpha spectroscopy with CIRPASS
Michelle Doherty, Andrew Bunker, Robert Sharp +3
We have conducted an H-alpha survey of 38 0.77<z<1 galaxies over ~100 arcmin^2 of the Hubble Deep Field North and Flanking Fields, to determine star formation rates (SFRs), with th…
The Las Campanas Infra-red Survey. V. Keck Spectroscopy of a large sample of Extremely Red Objects
M. Doherty, A. J. Bunker, R. S. Ellis +1
(Abridged) We present deep Keck spectroscopy, using the DEIMOS and LRIS spectrographs, of a large and representative sample of 67 ``Extremely Red Objects'' (EROs) to H=20.5, with I…
