Particle Acceleration and Cosmic-Ray Origin in the Galaxy
In 1990’s Very High Energy Gamma-ray Astrophysics has dramatically advanced due to the Imaging Air Čerenkov Telescopes(IACTs). After the first detection of TeV gamma-ray emission from the Crab nebula in 1989, several type of TeV gamma-ray sources, Active Galactic Nuclei(AGN), young pulsar, and SuperNova Remnant(SNR), have been detected. In those discoveries, recent detections of both synchrotro...
متن کاملProbing the Origin of the Cosmic Acceleration with the Subaru/FMOS Cosmological Redshift Survey
We propose the first large-scale cosmological redshift survey of the z > 1 Universe using the newly commissioned FMOS wide-field spectrograph in order to test for predicted gravitational departures from General Relativity in the early Universe. Spectroscopic redshifts will be secured using the Hα emission line for 20,000 galaxies with 0.7 < z < 1.6 over 30 deg by the target selection method tha...
متن کاملRadio Galaxy Clustering at z ∼ 0.3
Radio galaxies are uniquely useful as probes of large-scale structure as their uniform identification with giant elliptical galaxies out to high redshift means that the evolution of their bias factor can be predicted. As the initial stage in a project to study large-scale structure with radio galaxies we have performed a small redshift survey, selecting 29 radio galaxies in the range 0.19 < z <...
متن کاملProbing the nature of cosmic acceleration
The cosmic acceleration is one of the most significant cosmological discoveries over the last century. The two categories of explanation are exotic component (dark energy) and modified gravity. We constrain the two types of model by a joint analysis with perturbation growth and direct H(z) data. Though the minimal χ of the ΛCDM is almost the same as that of DGP, in the sense of consistency we f...
متن کاملProbing the faint end of the Galaxy luminosity function at z = 3 with Ly α emission ⋆
We present spectroscopic observations obtained with the ESO Very Large Telecope (VLT) of seven candidate Lyα emitting galaxies in the field of the radio quiet Q1205-30 at z=3.04 previously detected with deep narrow band imaging. Based on equivalent widths and limits on line ratios we confirm that all seven objects are Lyα emitting galaxies. Deep images also obtained with the VLT in the B and I ...
