The nearby radio galaxy M87 offers a unique opportunity for exploring the connection between gamma-ray production and jet formation at an unprecedented linear resolution. However,…
Galaxy evolution in the mid-infrared green valley: a case of the A2199 supercluster
Gwang-Ho Lee, Ho Seong Hwang, Myung Gyoon Lee +4
We study the mid-infrared (MIR) properties of the galaxies in the A2199 supercluster at z = 0.03 to understand the star formation activity of galaxy groups and clusters in the supe…
Dust from Comet 209P/LINEAR during its 2014 Return: Parent Body of a New Meteor Shower, the May Camelopardalids
Masateru Ishiguro, Daisuke Kuroda, Hidekazu Hanayama +29
We report a new observation of the Jupiter-family comet 209P/LINEAR during its 2014 return. The comet is recognized as a dust source of a new meteor shower, the May Camelopardalids…
Unveiling acoustic physics of the CMB using nonparametric estimation of the temperature angular power spectrum for Planck
Amir Aghamousa, Arman Shafieloo, Mihir Arjunwadkar +1
Estimation of the angular power spectrum is one of the important steps in Cosmic Microwave Background (CMB) data analysis. Here, we present a nonparametric estimate of the temperat…
A Fanaroff-Riley Type I Candidate in Narrow-Line Seyfert 1 Galaxy Mrk 1239
Akihiro Doi, Kiyoaki Wajima, Yoshiaki Hagiwara +1
We report finding kiloparsec-scale radio emissions aligned with parsec-scale jet structures in the narrow-line Seyfert 1 (NLS1) galaxy Mrk 1239 using the Very Large Array and the V…
Intrinsic Brightness Temperatures of Compact Radio Jets as a Function of Frequency
Sang-Sung Lee
We present results of our investigation of the radio intrinsic brightness temperatures of compact radio jets. The intrinsic brightness temperatures of about 100 compact radio jets…
Kepler photometry of RRc stars: peculiar double-mode pulsations and period doubling
P. Moskalik, R. Smolec, K. Kolenberg +11
We present the analysis of four first overtone RR Lyrae stars observed with the Kepler space telescope, based on data obtained over nearly 2.5yr. All four stars are found to be mul…
Low-resolution Spectroscopy for the Globular Clusters with Signs of Supernova Enrichment: M22, NGC 1851 and NGC 288
Dongwook Lim, Sang-Il Han, Young-Wook Lee +5
There is increasing evidence for the presence of multiple red giant branches (RGBs) in the color-magnitude diagrams of massive globular clusters (GCs). In order to investigate the…
Baryon Content of Massive Galaxy Clusters (0.57 < z < 1.33)

A Measurement of Gravitational Lensing of the Cosmic Microwave Background by Galaxy Clusters Using Data from the South Pole Telescope
E. J. Baxter, R. Keisler, S. Dodelson +72
Clusters of galaxies are expected to gravitationally lens the cosmic microwave background (CMB) and thereby generate a distinct signal in the CMB on arcminute scales. Measurements…
