SUMMARY:Anna Patej (Harvard) "Distributions of Baryons from the Virial Radius of Galaxy Clusters to Large Scales"
DESCRIPTION:Abstract:\nI will discuss my recent work on the distributions of baryonic matter on various scales\, from the gas and galaxies in galaxy clusters to the clustering of massive galaxies on large scales. Near the virial radius of galaxy clusters\, long-standing analytical models of structure formation as well as recent simulations predict the existence of steep density jumps in the gas and dark matter profiles. I will describe a new method for deriving models for the gas distribution in galaxy clusters\, which relies on a few basic assumptions — including the existence of such density jumps — and show a resulting profile for the gas that is in good agreement with X-ray observations of cluster interiors and simulations of the outskirts.\nSince cluster member galaxies are expected to follow similar collisionless dynamics as the dark matter\, the galaxy density profile should show a steep density jump as well. I will address the question of whether we can find evidence for a feature consistent with a density jump with current observations\, and will additionally discuss avenues for probing the density jumps with future data sets.\nMoving to larger scales where massive galaxies of different types are expected to roughly trace the same large-scale structure\, I will present a test of this prediction by measuring the clustering of red and blue galaxies at z~0.6 using the CMASS sample of galaxies from DR12 of SDSS-III. The stochasticity between these two samples can be quantified via the correlation coefficient r\, which can be constructed from two different statistics\, both of which indicate that on intermediate scales (20 < R < 100 Mpc/h) there is low stochasticity between the two samples of galaxies.\nLastly\, I will describe some ongoing and future observational efforts\, focusing on my involvement with the DECam Legacy Survey (DECaLS)\, a pathfinder imaging survey for the upcoming Dark Energy Spectroscopic Instrument (DESI) galaxy redshift survey.\nSlides

SUMMARY:Sara Simon (Princeton) "The Atacama B-Mode Search: Cosmic Microwave Background Polarimetry at 17\,000 Feet"
DESCRIPTION:Abstract:\nThe Atacama B-mode Search (ABS) was a crossed-Dragone telescope located at an elevation of 5200 m in the Atacama Desert in Chile that observed the cosmic microwave background (CMB) from February 2012 until October 2014. ABS searched for the primordial B-mode polarization signal at large angular scales from multipole moments of l~40 to l~500\, where it is expected to peak. The ABS focal plane consisted of 240 pixels sensitive to 145 GHz\, each containing two transition-edge sensor bolometers coupled to orthogonal polarizations. Cold optics and a warm\, rapidly rotating half-wave plate made the ABS instrument unique. I will discuss the ABS instrument and its contributions to the field of CMB cosmology.

SUMMARY:Sheldon Stone (Syracuse Univ.) "Pentaquarks and Tetraquarks at LHCb"
DESCRIPTION:Abstract: \nI will discuss the discovery of two pentaquark states both decaying into a J/ψ meson and a proton. The decay mode defines the quark content as c cbar\, u\, u\, d\, and thus are called charmonium pentaquarks. These exotic structures are found in Λb→J/ψ K- p decays whose existence and properties are determined from a full amplitude analysis using 7 and 8 TeV pp collision data corresponding to an integrated luminosity of 3/fb collected by the LHCb experiment. The two states will be shown to be of opposite parity and have spins 3/2 and 5/2. I will also present a determination of spin parity of the the Z(4430) tetraquark meson\, also a charmonium state. Finally different models of pentaquark structure will be discussed.
