A Sub-Earth-Mass Moon Orbiting a Gas Giant Primary or a High Velocity Planetary System in the Galactic Bulge
D. P. Bennett, V. Batista, I. A. Bond +90
We present the first microlensing candidate for a free-floating exoplanet-exomoon system, MOA-2011-BLG-262, with a primary lens mass of M_host ~ 4 Jupiter masses hosting a sub-Eart…
Phosphorus in the Young Supernova Remnant Cassiopeia A
Bon-Chul Koo, Yong-Hyun Lee, Dae-Sik Moon +2
Phosphorus (P), which is essential for life, is thought to be synthesized in massive stars and dispersed into interstellar space when these stars explode as supernovae (SNe)…
Intrinsic Brightness Temperature of Compact Radio Sources at 86 GHz
Sang-Sung Lee
We present results on the intrinsic brightness temperature of a sample of compact radio sources observed at 86 GHz using the Global Millimeter VLBI Array. We use the observed brigh…
Physical properties and transmission spectrum of the WASP-80 planetary system from multi-colour photometry
L. Mancini, J. Southworth, S. Ciceri +29
WASP-80 is one of only two systems known to contain a hot Jupiter which transits its M-dwarf host star. We present eight light curves of one transit event, obtained simultaneously…
Observational Constraints on Redshift Remapping
Bruce A. Bassett, Yabebal Fantaye, Renée Hložek +2
There are two redshifts in cosmology: , the observed redshift computed via spectral lines, and the model redshift, , defined by the effective FLRW scale factor. In gene…
The optical rebrightening of GRB100814A: an interplay of forward and reverse shocks?
Massimiliano De Pasquale, N. P. M. Kuin, S. Oates +36
We present a wide dataset of gamma-ray, X-ray, UVOIR, and radio observations of the Swift GRB100814A. At the end of the slow decline phase of the X-ray and optical afterglow, this…
ARRAKIS: Atlas of Resonance Rings As Known In the S4G
S. Comerón, H. Salo, E. Laurikainen +19
Resonance rings are the consequence of secular evolution processes that redistribute material and angular momentum in discs. We produced a Catalogue and an Atlas of the rings detec…
Long-term monitoring of Sgr A* at 7 mm with VERA and KaVA
Kazunori Akiyama, Motoki Kino, Bong Won Sohn +3
We present the results of radio monitoring observations of Sgr A* at 7 mm (i.e. 43 GHz) with VLBI Exploration of Radio Astrometry (VERA), which is a VLBI array in Japan. VERA provi…
Rotational properties of Maria asteroid family
Myung-Jin Kim, Young-Jun Choi, Hong-Kyu Moon +13
Maria family is regarded as an old-type (~3 +/- 1 Gyr) asteroid family which has experienced substantial collisional and dynamical evolution in the Main-belt. It is located nearby…
Cosmological Constraints from the Anisotropic Clustering Analysis using BOSS DR9
Eric V. Linder, MinJi Oh, Teppei Okumura +2
Our observations of the Universe are fundamentally anisotropic, with data from galaxies separated transverse to the line of sight coming from the same epoch while that from galaxie…
Observations of 6.7 GHz Methanol Masers with EAVN I: VLBI Images of the first Epoch of Observations
Kenta Fujisawa, Koichiro Sugiyama, Kazuhito Motogi +26
Very long baseline interferometry (VLBI) monitoring of the 6.7 GHz methanol maser allows us to measure the internal proper motions of the maser spots and therefore study the gas mo…
Monitoring of multi-frequency polarization of gamma-ray bright AGNs
Sang-Sung Lee, Myounghee Han, Sincheol Kang +5
We started two observing programs with the Korean VLBI Network (KVN) monitoring changes in the flux density and polarization of relativistic jets in gamma-ray bright AGNs simultane…
The relationship between radio power at 22 and 43 GHz and black hole properties of AGN in elliptical galaxies
Songyoun Park, Bong Won Sohn, Sukyoung K. Yi
We investigate the relationship between radio power and properties related to active galactic nuclei (AGNs). Radio power at 1.4 or 5 GHz, which has been used in many studies, can b…
Revisiting the proposed circumbinary multi-planet system NSVS14256825
Tobias C. Hinse, Jae Woo Lee, Krzysztof Gozdziewski +2
In this work we carry out an analysis of the observed times of primary and secondary eclipses of the post-common envelope binary NSVS14256825. Recently, \cite{Almeida2013} proposed…
An hourglass model for the flare of HST-1 in M87
Wen-Po Liu, Guang-Yao Zhao, Yong Jun Chen +2
To explain the multi-wavelength light curves (from radio to X-ray) of HST-1 in the M87 jet, we propose an hourglass model that is a modified two-zone system of Tavecchio & Ghiselli…
Towards a better understanding of the distance scale from RR Lyrae variable stars: A case study for the inner halo globular cluster NGC 6723
Jae-Woo Lee, Mercedes Lopez-Morales, Kyeong-Soo Hong +3
We present BV photometry for 54 variables in the metal-rich inner halo globular cluster NGC6723. With the discovery of new RR Lyrae variables (RRLs), we obtain <P_ab> = 0.541 +/- 0…
