An extreme EXO: a type 2 QSO at z=1.87

A. Del Moro, M. G. Watson, S. Mateos +6

We aim to understand the multi-wavelength properties of 2XMM J123204+215255, the source with the most extreme X-ray-to-optical flux ratio amongst a sample of bright X-ray selected…

The Stellar Populations of Lyman Break Galaxies at

Kiyoto Yabe, Kouji Ohta, Ikuru Iwata +4

We present the results of Spectral Energy Distribution (SED) fitting analysis for Lyman Break Galaxies (LBGs) at in the GOODS-N and its flanking fields. From the SED fitti…

Adaptive Optics Imaging of Lyman Break Galaxies as Progenitors of Spheroids in the Local Universe

M. Akiyama, Y. Minowa, N. Kobayashi +2

In order to reveal the stellar mass distribution of z~3 galaxies, we are conducting deep imaging observations of U-dropout Lyman Break Galaxies (LBGs) with Adaptive Optics (AO) sys…

A Revised Estimate of the CO (J=1-0) Emission from the Host Galaxy of GRB 030329 Using the Nobeyama Millimeter Array

Akira Endo, Kotaro Kohno, Bunyo Hatsukade +9

A sensitive observation of the CO (J=1-0) molecular line emission in the host galaxy of GRB 030329 (z =0.1685) has been performed using the Nobeyama Millimeter Array in order to de…

Differential Evolution of the UV Luminosity Function of Lyman Break Galaxies from z~5 to 3

I. Iwata, K. Ohta, N. Tamura +5

(abridged) We report the UV luminosity function (LF) of Lyman break galaxies at z~5 derived from a deep and wide survey using the Subaru/Suprime-Cam. Target fields consist of two b…
