CMB Temperature and Matter Power Spectrum in a Decay Vacuum Dark Energy Model
Lixin Xu, Yuting Wang, Hyerim Noh
In this paper, a decay vacuum model is revisited by detailed analysis of background evolution and perturbation equations. We show the imprints on CMB tempera…
The Cosmic Infrared Background Experiment (CIBER): The Low Resolution Spectrometer

The Cosmic Infrared Background Experiment (CIBER) is a suite of four instruments designed to study the near infrared (IR) background light from above the Earth's atmosphere. The in…
Diversity of multiwavelength emission bumps in the GRB 100219A afterglow
J. Mao, D. Malesani, P. D'Avanzo +4
Context. Multi-wavelength observations of gamma-ray burst (GRB) afterglows provide important information about the activity of their central engines and their environments. In part…
Searching for the first stars with the Gaia mission
Rafael S. de Souza, Alberto Krone-Martins, Emille E. O. Ishida +1
We construct a theoretical model to predict the number of orphan afterglows (OA) from gamma-ray bursts (GRBs) triggered by primordial metal-free (Pop III) stars expected to be obse…
Unified Dark Fluid with Constant Adiabatic Sound Speed and Cosmic Constraints
Lixin Xu, Yuting Wang, Hyerim Noh
As is known above 90% of the energy content in Universe is made of unknown dark component. Usually this dark fluid is separated into two parts: dark matter and dark energy. However…
Magnetic Field Strength in the Upper Solar Corona Using White-light Shock Structures Surrounding Coronal Mass Ejections
R. -S. Kim, N. Gopalswamy, Y. -J. Moon +2
To measure the magnetic field strength in the solar corona, we examined 10 fast (> 1000 km/s) limb CMEs which show clear shock structures in SOHO/LASCO images. By applying piston-s…
New Light-Travel Time Models and Orbital Stability Study of the Proposed Planetary System HU Aquarii
Tobias C. Hinse, Jae Woo Lee, Krzysztof Gozdziewski +3
In this work we propose a new orbital architecture for the two proposed circumbinary planets around the polar eclipsing binary HU Aquarii. We base the new two-planet, light-travel…
AKARI Observation of the North Ecliptic Pole (NEP) Supercluster at z = 0.087: mid-infrared view of transition galaxies
Jongwan Ko, Myungshin Im, Hyung Mok Lee +12
We present the mid-infrared (MIR) properties of galaxies within a supercluster in the North Ecliptic Pole region at z?0.087 observed with the AKARI satellite. We use data from the…
GRB 081029: A Gamma-Ray Burst with a Multi-Component Afterglow
Stephen T. Holland, Massimiliano De Pasquale, Jirong Mao +12
We present an analysis of the unusual optical light curve of the gamma-ray burst GRB 081029, a long-soft burst with a redshift of z = 3.8479. We combine X-ray and optical observati…
Coupled HBO and NBO variations in the Z source GX 5-1: inner accretion disk as the location of QPOs
K. Sriram, A. R. Rao, C. S. Choi
The simultaneous and coupled evolution of horizontal branch oscillation (HBO) and normal branch oscillation (NBO) in Z-type sources suggests that the production of HBO is connected…
Initiation of CME and Associated Flare Caused by Helical Kink Instability Observed by SDO/AIA
Pankaj Kumar, K. -S. Cho, S. -C. Bong +2
In this paper, we present multiwavelength observations of helical kink instability as a trigger of a CME which occurred in AR NOAA 11163 on 24 February 2011. The CME was associated…
A Planetary Companion to the Intermediate-Mass Giant HD 100655
Masashi Omiya, Inwoo Han, Hideyuki Izumiura +10
A precise radial velocity survey conducted by a Korean-Japanese planet search program revealed a planetary companion around the intermediate-mass clump giant HD 100655. The radial…
The Algol System SZ Herculis: Physical Nature and Orbital Behavior
Jae Woo Lee, Chung-Uk Lee, Seung-Lee Kim +2
Multiband CCD photometric observations of SZ Her were obtained between 2008 February and May. The light curve was completely covered and indicated a significant temperature differe…
Comparison of the Diffuse Halpha and FUV Continuum Backgrounds: On the Origins of the Diffuse Halpha Background
Kwang-Il Seon, Adolf Witt, Il-Joong Kim +4
We compare the diffuse H map of our Galaxy with the FUV (1370-1710Å) continuum map. The H intensity correlates well with the FUV intensity. The H/FUV intensity ratio incre…
