    "The AGN Channel For LIGO Black Hole Binary Mergers"

    Abstract: I will present a model for stellar mass black hole binary (BHB) mergers accelerated by an active galactic nucleus (AGN) accretion disk. This model predicted the existence of overweight' stellar mass BHB mergers, detectable by LIGO (McKernan, Ford, et al. 2014). In more recent work, we find the rate of BHB merger by this channel can span the range 1e-4-1e3 Gpc^-3 yr^-1, depending on a variety of poorly constrained astrophysical parameters. Thus, with LIGO's measured rates (12-213 Gpc^-3 yr^-1), we can already...

    "New View of Heliosphere: “Heliosphere with Jets”; Turbulence; Reconnection – lessons learned from Voyager, Cassini, IBEX, TeV Cosmic Rays about our home in the galaxy"

    Abstract:  In this talk, I will discuss what did we recently learned from the in-situ measurements from Voyager spacecrafts as well as the remote sensing of energetic neutral atoms from CASSINI, IBEX and the anisotropy of TeV cosmic rays about the heliosphere. The heliosphere is the only local example of astrosphere that can be probed in such details. The very shape of the heliosphere is being...

    "Characterizing the population of pulsars in the Galactic bulge with the Fermi Large Area Telescope"
     

    ABSTRACT: Several groups have demonstrated the existence of an excess in the gamma-ray emission around the Galactic Center (GC) with respect to the predictions from a variety of Galactic Interstellar Emission Models (GIEMs) and point source catalogs. The origin of this excess, peaked at a few GeV, is still under debate. A possible interpretation is that it comes from a population of unresolved Millisecond Pulsars (MSPs) in the Galactic bulge. We investigate the...

    "ALMA polarization of HL Tau - investigating the planet formation"

    Abstract:  Constraining the grain size in protoplanetary disks is a key to understanding the first stage of planet formation. The grain size has been estimated by measuring the spectral index at millimeter wavelengths, while it has huge uncertainties. We have proposed that millimeter-wave polarization is another method to constrain the grain size. We show that thermal dust emission is scattered off of other dust grains and the residual polarization is up to 2.5 %, which is detectable with ALMA. This self-...
