"Brightest Cluster Galaxies as probes of galaxy formation"

Paola Oliva (Swinburne University, Australia)

Abstract
Brightest group and cluster galaxies (BGGs/BCGs) are old giant ellipticals, which have been shown to be different from any other cluster galaxy. Despite of being easy detectable their formation and evolution is still poorly understood. I will present a statistical analysis of a large sample of 883 Brightest group and cluster galaxies (BGGs/BCGs) from the Galaxy and Mass Assembly Survey (GAMA). We analyse their stellar mass growth, position in the cluster, and the percentage of BGGs/BCGs that show H\alpha in emission. We find that BCGs grow steeply until z~0.5, and slow down at lower redshift.

BCGs have been predicted to have a more active accretion history than less massive galaxies. We further use IFU spectroscopy to study the spatially-resolved stellar populations of BCGs and their connection with galaxy's angular momentum. We find that all the BCGs in our sample have gone through at least one major merger after z=1. Our stellar population analysis suggest that BCGs have a more active accretion history than early-type galaxies of similar mass.

"Brightest Prospects in Hadron Spectroscopy"

Vincent Mathieu (Indiana Univ., USA; Cluster guest)

Abstract
There are several experiments in Europe (COMPASS, LHCb), USA (CLAS, GlueX) and Asia (BES, Belle) devoted to hadron spectroscopy. In this talk, their goals and prospects are presented with a special emphasis on the discovery of new 'exotic' resonances. There are indeed indications from these experiments about resonances (hybrid mesons, glueballs, tetraquarks, etc.) beyond the quark model classification. However, a close collaboration between theorists and experimentalists is necessary to draw robust conclusions about their existence. Vincent will review the theoretical developments necessary to fully exploit the data provided by the experiments and finally reach their objectives.

"What drives the evolution of the Milky Way's disk?"

Jo Bovy

Abstract
Observations of the structure and dynamics of different stellar populations in the Milky Way's disk provide a unique perspective on disk formation, evolution, and dynamics. I will review our current knowledge of the chemo-orbital structure of the disk. I will then discuss new measurements of the kinematics and chemistry of intermediate-age stars over a large part of the Galactic disk from the APOGEE survey and the new insights these measurements provide about the formation and evolution of the disk.

"Particle Physics meets Astrophysics: Astrophysical counterparts of IceCube neutrinos""

Elisa Resconi (TUM) and Paolo Padovani (ESO)

Abstract
IceCube has recently reported the discovery of high-energy neutrinos of astrophysical origin, opening up the PeV (10^15 eV) sky. These observations are challenging to interpret on the astronomical side and have triggered a fruitful intra-cluster collaboration across particle and astro-physics. Elisa (TUM) and Paolo (ESO) will first describe the IceCube experiment and then, by using positional and energetic diagnostics, discuss plausible astronomical counterparts to the neutrino events. These include extragalactic sources, namely BL Lacertae objects, a sub-class of blazars, and Galactic pulsar wind nebulae. They will conclude by addressing the implications of our results and possible ways forward.

"Searching for the origins of galaxy bimodality"

Vivienne Wild (University of St. Andrews, UK)

Abstract
Understanding how and why galaxies form and evolve is one of the most challenging problems in modern astrophysics. Our own galaxy, the Milky Way, shows order and structure, as do most massive galaxies in our local neighbourhood. Yet when we look to very distant galaxies they are disordered and chaotic. One leading theory for the origin of this transformation invokes gas-rich mergers, which trigger massive starbursts leading to bulge and supermassive black hole growth. I will start by reviewing the evidence for and against this scenario. I will then turn to the interesting case of post-starburst galaxies at 0<z<2. How many of these recently quenched descendents of massive starbursts could be the progenitors of modern day red ellipticals, and what fraction of red ellipticals could have been formed through the gas-rich mergers required to trigger such strong starbursts?
