Robaina, Aday R., Bell, Eric F., Skelton, Rosalind E., McIntosh, Daniel H., Somerville, Rachel S., Zheng, Xianzhong, ...
Both observations and simulations show that major tidal interactions or mergers between gas-rich galaxies can lead to intense bursts of starformation. Yet, the average enhancement in star formation...
Wolf, Christian, Aragón-Salamanca, Alfonso, Balogh, Michael, Barden, Marco, Bell, Eric F., Gray, Meghan E., ...
Galaxies migrate from the blue cloud to the red sequence when their star formation is quenched. Here, we report on galaxies quenched by environmental effects and not by mergers or strong AGN as often...
A spectroscopic measure of the star-formation rate density in dwarf galaxies at z~1 (2009)
Davies, G. T., Gilbank, David, Glazebrook, Karl, Bower, Richard, Baldry, I. K., Balogh, Michael, ...
We use a K-selected (22.5 < K_AB < 24.0) sample of dwarf galaxies (8.4 < log(M*/Msun) < 10) at 0.89

We investigate the properties of optically passive spirals and dusty red galaxies in the A901/2 cluster complex at redshift ~0.17 using restframe near-UV-optical SEDs, 24 micron IR data and HST...
STAGES: the Space Telescope A901/2 Galaxy Evolution Survey (2008)
Gray, M. E., Wolf, Christian, Barden, Marco, Peng, Chien Y., Haeussler, Boris, Bell, Eric F., ...
We present an overview of the Space Telescope A901/2 Galaxy Evolution Survey (STAGES). STAGES is a multiwavelength project designed to probe physical drivers of galaxy evolution across a wide range...
Heymans, Catherine, Gray, Meghan E., Peng, Chien Y., Van Waerbeke, Ludovic, Bell, Eric F., Wolf, Christian, ...
We present a high resolution dark matter reconstruction of the z=0.165 Abell 901/902 supercluster from a weak lensing analysis of the HST STAGES survey. We detect the four main structures of the...

Hau, George, Bower, Richard, Kilborn, Virginia, Forbes, Duncan, Balogh, Michael, Oosterloo, Tom
A common feature of hierarchical galaxy formation models is the process of "inverse" morphological transformation: a bulge dominated galaxy accretes a gas disk, dramatically reducing the system's...
Entropy generation in merging galaxy clusters (2007)
Balogh, Michael, McCarthy, Ian, Bower, Richard, Voit, G. Mark
In McCarthy et al. (2007, astro-ph/0701335) we present an analysis of entropy generation during cluster mergers, using SPH simulations. This conference proceeding contribution summarizes some of the...
GMOS Integral Field Spectroscopy of a Merging System with Enhanced Balmer Absorption (2004)
Swinbank, Mark, Balogh, Michael, Bower, Richard, Hau, George, Allington-Smith, Jeremy, Nichol, Robert, ...
In this paper we present the three dimensional dynamics of the galaxy SDSS J101345.39+011613.66, selected for its unusually strong Balmer absorption lines (Wo(H-delta)=7.5A). Using the GMOS-South IFU...
A Panoramic Halpha Imaging Survey of the z=0.4 cluster Cl0024.0+1652 with Subaru (2004)
Kodama, Tadayuki, Balogh, Michael, Smail, Ian, Bower, Richard, Nakata, Fumiaki
We employ panoramic, multicolour (BRz') and narrow-band Halpha imaging of the cluster Cl0024.0+1652 (z=0.39) from Subaru covering a ~30 arcmin field, to determine cluster membership and star...
De Propris, Roberto, Colless, Matthew, Peacock, John, Couch, Warrick, Driver, Simon, Balogh, Michael, ...
We derive the fraction of blue galaxies in a sample of clusters at z < 0.11 and the general field at the same redshift. The value of the blue fraction is observed to depend on the luminosity limit...
Quenching Cluster Cooling Flows with Recurrent Hot Plasma Bubbles (2004)
Vecchia, Claudio Dalla, Bower, Richard, Theuns, Tom, Balogh, Michael, Mazzotta, Pasquale, Frenk, Carlos S.
The observed cooling rate of hot gas in clusters is much lower than that inferred from the gas density profiles. This suggests that the gas is being heated by some source. We use an adaptive-mesh...

Galaxy ecology: groups and low-density environments in the SDSS and 2dFGRS (2003)
Balogh, Michael, Eke, Vince, Miller, Chris, Lewis, Ian, Bower, Richard, Couch, Warrick, ...
We analyse the observed correlation between galaxy environment and H-alpha emission line strength, using volume-limited samples and group catalogues of 24968 galaxies drawn from the 2dF Galaxy...
Gomez, Percy, Nichol, Robert, Miller, Chris, Balogh, Michael, Goto, Tomotsugu, Zabludoff, Ann, ...
(Abridged) We present in this paper a detailed analysis of the effect of environment on the star-formation activity of galaxies within the EDR of the SDSS. We have used the Halpha emission line to...
An H-alpha survey of the rich cluster A1689 (2002)
Balogh, Michael, Couch, Warrick J., Smail, Ian, Bower, Richard G., Glazebrook, Karl
(Abridged) We present results of an H-alpha survey in the rich cluster A1689 at z=0.18, using the LDSS++ spectrograph on the AAT. We obtained spectra covering redshifted H-alpha for 522 galaxies...

(Abridged) We present a morphological analysis of 17 X-ray selected clusters at z~0.25, imaged uniformly with HST WFPC2. Eight of these clusters have low X-ray luminosities (10^{45} ergs/s. The...
Revisiting the Cosmic Cooling Crisis (2001)
Balogh, Michael, Pearce, Frazer, Bower, Richard, Kay, Scott
Recent measurements of the K-band luminosity function now provide us with strong, reliable constraints on the fraction of baryons which have cooled. Globally, this fraction is only about 5%, and...

Balogh, Michael, Christlein, Daniel, Zabludoff, Ann, Zaritsky, Dennis
We investigate the dependence of the galaxy infrared luminosity function (LF) and the associated stellar mass function (SMF) on environment and spectral type using photometry from the Two Micron All...
