August 7 Supermassive Black Holes and their Host Dark Matter Halos
Suchetana Chatterjee (Presidency University)

Through a plethora of observational results we now know that there is a supermassive black hole (SMBH) at the center of every galaxy in the Universe. A fraction of these harbor an active accretion disc, and are known as active galactic nuclei (AGN). Thus in the paradigm of structure formation we would like to address the question of relating SMBH to their host dark matter halos. Observationally by studying the spatial clustering of SMBH or AGN we can infer information about their dark matter hosts. AGN clustering can be characterized within a powerful theoretical framework known as the Halo Occupation Distribution (HOD). In this talk, I shall discuss HOD modeling of AGN using a fully cosmological simulation and show that the underlying theoretical model fits the two-point correlation function (2PCF) of different types of AGN. This provides us an evolutionary picture of AGN along with dark matter halos over cosmic time. In the latter half of the talk I shall provide some limitations of the 2PCF fitting method and provide alternative ways to measure the HOD of AGN while trying to address some fundamental questions in AGN physics from a cosmological point-of-view.

September 25 The Puzzle of Anolamous Isotope Effect in High and Low Tc Superconductors
Prof. Guang-Lin Zhao (Southern University, Baton Rouge)

Abstract TBD

October 16 Thirty Meter Telescope: The Next Generation of Ground Based Optical/Infra Red Observatory
Warren Skidmore (Thirty Meter Telescope Observatory Corporation)

After a short construction status update I will discuss some of the observational capabilities that the Thirty Meter Telescope will provide and some of the areas of study that will benefit from the TMT's capabilities. I'll describe how the telescope design was developed to support a broad range of observing capabilities and how the observatory is being engineered. Finally I'll describe the avenues through which astronomers can actively participate in the project; in the planning for a potential TMT/NSF partnership, preparing for the development of 2nd generation instruments and directing the scientific aims for the observatory.
