Visitors Program

We maintain an active program for visiting scholars. BCCP hosts visitors at all levels, from senior scientists to postdocs, graduate students, and undergraduates. If you would like to visit BCCP, please fill out the form here.

Longer term visits involving collaborative activities with BCCP members are especially encouraged. BCCP can provide financial support for longer term visitors working with BCCP members on BCCP related projects. The applications are reviewed by a committee several times a year. All decisions are based on the availability of space and funding.

Special SSL Seminar
Location: SSL Addition conference room – 11a.m.
Speaker: Guido Risaliti (INAF, Italy / Harvard-Smithsonian CfA)
Title:  AGN Physics with NuSTAR: measuring black hole spins, complex absorption, and coronal properties.
Abstract: I will show some of the latest results based on NuSTAR observations of AGNs. I will focus on the new measurements for which the advent of NuSTAR has been fundamental, and in particular on the determination of the spin of a few supermassive black holes. I will show that the high quality spectra above 10 keV provided by NuSTAR can solve the long-standing problem of the degeneracy between absorption and reflection components in AGN, allowing a precise and unambiguous determination of the black hole spin, and a complete characterization of the complex and variable circumnuclear absorption. I will also briefly show how NuSTAR can unveil the geometry and structure of Compton-thick absorbers in type 2 AGNs, and measure the coronal properties of the brightest unobscured AGN.

Cosmology/BCCP seminar
Location: Hearst Field Annex B-1  – 1:10 p.m.
Speaker: Sirio Belli, Caltech
Title: Deep Keck spectroscopy of 1 < z < 2.5 quiescent galaxies: constraining the size growth and the mass assembly of the red sequence
Abstract: The most effective probe of the physical nature of quiescent galaxies is absorption line spectroscopy, which is particularly challenging at high redshift. Using the improved sensitivity of optical and infrared detectors at the Keck observatory, and the multiplex advantage of its new MOSFIRE spectrograph, we have undertaken a new spectroscopic survey of over 100 galaxies selected according to stellar mass and rest-frame optical color in the redshift range 1 < z < 2.5. Velocity dispersions and stellar ages derived from our spectra, together with HST-based sizes, provide valuable insight into the mass assembly of quiescent galaxies. We find that the stellar to dynamical mass ratio evolves with redshift, which might imply a change in the dark matter fraction or in the stellar initial mass function. We also find that recently quenched galaxies are systematically larger in size, which enables us to quantify how “progenitor bias” contributes to the observed size evolution. We conclude that at least half of the size evolution of the red sequence observed at z~1.5 is due to physical growth of individual galaxies.
