The HST/ACS Coma Cluster Survey: I - Survey Objectives and Design (2008)

Carter, David, Goudfrooij, Paul, Mobasher, Bahram, Ferguson, Henry C., Puzia, Thomas H., Aguerri, Alfonso L., ...

We describe the HST ACS Coma cluster Treasury survey, a deep two-passband imaging survey of one of the nearest rich clusters of galaxies, the Coma cluster (Abell 1656). The survey was designed to...

Supermassive black holes in the Sbc spiral galaxies NGC 3310, NGC 4303 and NGC 4258 (2007)

Pastorini, Guia, Marconi, Alessandro, Capetti, Alessandro, Axon, David J., Alonso-Herrero, Almudena, Atkinson, John, ...

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$\alpha$ $\lambda$ $6564 \AA$,...

Dominant Nuclear Outflow Driving Mechanisms in Powerful Radio Galaxies (2007)

Batcheldor, Dan, Tadhunter, Clive, Holt, Joanna, Morganti, Raffaella, O'Dea, Christopher P., Axon, David J., ...

In order to identify the dominant nuclear outflow mechanisms in Active Galactic Nuclei, we have undertaken deep, high resolution observations of two compact radio sources (PKS 1549-79 and PKS...

How Special are Brightest Cluster Galaxies? The Impact of Near-Infrared Luminosities on Scaling Relations for BCGs (2006)

Batcheldor, Dan, Marconi, Alessandro, Merritt, David, Axon, David J.

Using the extended J, H and K magnitudes provided by the 2MASS data archive, we consider the position of brightest cluster galaxies (BCGs) in the observed relations between inferred supermassive...

The nature of the HE0450-2958 System (2005)

Merritt, David, Bergmann, Thaisa Storchi, Robinson, Andrew, Batcheldor, Dan, Axon, David, Fernandes, Roberto Cid

Magain et al. (2005) argued that the host galaxy of the quasar in HE0450-2958 is substantially under-luminous given the likely mass of its nuclear black hole. Using kinematical information from the...

Constraints on Jupiters from observations of Galactic Bulge microlensing events during 2000 (2002)

Tsapras, Yiannis, Horne, Keith, Carson, Richard, Alvarez, Javier Mendez, Batcheldor, Dan, Graham, Alister W., ...

We present observations of 8 Galactic Bulge microlensing events taken with the 1.0m JKT on La Palma during 2000 June and July. The JKT observing schedule was optimized using a prioritizing algorithm...
