Supermassive black holes in the Sbc spiral galaxies NGC 3310, NGC 4303 and NGC 4258

Guia Pastorini, Alessandro Marconi, Alessandro Capetti +12

We present new Space Telescope Imaging Spectrograph (STIS) observations of three spiral galaxies, NGC 4303, NGC 3310 and NGC 4258. The bright optical emission lines H $6564…

A general catalogue of 6.7GHz methanol masers II: statistical analysis

Michele R. Pestalozzi, A. Chrysostomou, J. Collett +3

Context: Methanol masers at 6.7GHz are recognised markers of high-mass star formation regions. The study of their distribution in the Galaxy gives important insights into the star…

OH megamasers, starburst and AGN activity in Markarian 231

A. M. S. Richards, J. H. Knapen, J. A. Yates +5

We present MERLIN observations of OH maser and radio continuum emission from the Ultra Luminous IR Galaxy Markarian 231. The 1665- and 1667-MHz transitions have a combined velocity…

Supermassive black hole mass measurements for NGC 1300 and NGC 2748 based on HST emission-line gas kinematics

J. W. Atkinson, J. L. Collett, A. Marconi +18

We present Space Telescope Imaging Spectrograph emission-line spectra of the central regions of the spiral galaxies NGC 1300 and NGC 2748. From the derived kinematics of the nuclea…

A new population of extended, luminous star clusters in the halo of M31

A. P. Huxor, N. R. Tanvir, M. J. Irwin +5

We present three new clusters discovered in the halo of M31 which, although having globular-like colours and luminosities,have an unusually large half-light radii, ~30 pc. They lie…
