Probing Intergalactic Neutral Hydrogen by the Lyman Alpha Red Damping Wing of Gamma-Ray Burst 130606A Afterglow Spectrum at z = 5.913
Tomonori Totani, Kentaro Aoki, Takashi Hattori +7
The unprecedentedly bright optical afterglow of GRB 130606A located by Swift at a redshift close to the reionization era (z = 5.913) provides a new opportunity to probe the ionizat…
Suzaku observations of the diffuse x-ray emission across the fermi bubbles' edges
J. Kataoka, M. Tahara, T. Totani +10
We present Suzaku X-ray observations along two edge regions of the Fermi Bubbles, with eight ~20 ksec pointings across the northern part of the North Polar Spur (NPS) surrounding t…
On the Systematic Errors of Cosmological-Scale Gravity Tests using Redshift Space Distortion: Non-linear Effects and the Halo Bias
Takashi Ishikawa, Tomonori Totani, Takahiro Nishimichi +3
Redshift space distortion (RSD) observed in galaxy redshift surveys is a powerful tool to test gravity theories on cosmological scales, but the systematic uncertainties must carefu…
A Study of Selection Methods for H alpha Emitting Galaxies at z~1.3 for the Subaru/FMOS Galaxy Redshift Survey for Cosmology (FastSound)
Motonari Tonegawa, Tomonori Totani, Masayuki Akiyama +9
The efficient selection of high-redshift emission galaxies is important for future large galaxy redshift surveys for cosmology. Here we describe the target selection methods for th…
The Cherenkov Telescope Array Large Size Telescope
G. Ambrosi, Y. Awane, H. Baba +129
The two arrays of the Very High Energy gamma-ray observatory Cherenkov Telescope Array (CTA) will include four Large Size Telescopes (LSTs) each with a 23 m diameter dish and 28 m…
Cosmological Fast Radio Bursts from Binary Neutron Star Mergers
Tomonori Totani
Fast radio bursts (FRBs) at cosmological distances have recently been discovered, whose duration is about milliseconds. We argue that the observed short duration is difficult to ex…
X-ray and Radio Follow-up Observations of High-Redshift Blazar Candidates in the Fermi-LAT Unassociated Source Population
Y. Takahashi, J. Kataoka, K. Niinuma +6
We report on the results of X-ray and radio follow-up observations of two GeV gamma-ray sources 2FGL J0923.5+1508 and 2FGL J1502.1+5548, selected as candidates for high-redshift bl…
Active Galactic Nuclei under the scrutiny of CTA
H. Sol, A. Zech, C. Boisson +24
Active Galactic Nuclei (hereafter AGN) produce powerful outflows which offer excellent conditions for efficient particle acceleration in internal and external shocks, turbulence, a…
Potential of EBL and cosmology studies with the Cherenkov Telescope Array
Daniel Mazin, Martin Raue, Bagmeet Behera +4
Very high energy (VHE, E >100 GeV) gamma-rays are absorbed via interaction with low-energy photons from the extragalactic background light (EBL) if the involved photon energies are…
