CLASH: Extreme Emission Line Galaxies and Their Implication on Selection of High-Redshift Galaxies
Xingxing Huang, Wei Zheng, Junxian Wang +23
We utilize the CLASH (Cluster Lensing And Supernova survey with Hubble) observations of 25 clusters to search for extreme emission-line galaxies (EELGs). The selections are carried…
Spiral Density Waves in M81. II. Hydrodynamic Simulations for Gas Response to Stellar Spiral Density Waves
Hsiang-Hsu Wang, Wing-Kit Lee, Ronald E. Taam +2
Gas response to the underlying stellar spirals is explored for M81 using unmagnetized hydrodynamic simulations. Constrained within the uncertainty of observations, 18 simulations a…
Two-size approximation: a simple way of treating the evolution of grain size distribution in galaxies
Hiroyuki Hirashita
Full calculations of the evolution of grain size distribution in galaxies are in general computationally heavy. In this paper, we propose a simple model of dust enrichment in a gal…
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…
Three-dimensional non-vacuum pulsar outer-gap model: Localized acceleration electric field in the higher altitudes
Kouichi Hirotani
We investigate the particle accelerator that arises in a rotating neutron-star magnetosphere. Solving the Poisson equation for the electro-static potential, the Boltzmann equations…
Compact formulae, dynamics and radiation of charged particles under synchro-curvature losses
Daniele Viganò, Diego F. Torres, Kouichi Hirotani +1
We consider the fundamental problem of charged particles moving along and around a curved magnetic field line, revising the synchro-curvature radiation formulae introduced by Cheng…
The Chandra Planetary Nebulae Survey (ChanPlaNS): III. X-ray Emission from the Central Stars of Planetary Nebulae
R. Montez, J. H. Kastner, B. Balick +25
We present X-ray spectral analysis of 20 point-like X-ray sources detected in Chandra Planetary Nebula Survey (ChanPlaNS) observations of 59 planetary nebulae (PNe) in the solar ne…
Active-Region Tilt Angles: Magnetic Versus White-Light Determinations of Joy's Law
Y. -M. Wang, R. C. Colaninno, T. Baranyi +1
The axes of solar active regions are inclined relative to the east--west direction, with the tilt angle tending to increase with latitude ("Joy's law"). Observational determination…
Observations of Infalling and Rotational Motions on a 1,000-AU Scale around 17 Class 0 and 0/I Protostars: Hints of Disk Growth and Magnetic Braking?
Hsi-Wei Yen, Patrick M. Koch, Shigehisa Takakuwa +3
We perform imaging and analyses of SMA 1.3 mm continuum, C18O (2-1) and 12CO (2-1) line data of 17 Class 0 and 0/I protostars to study their gas kinematics on a 1,000-AU scale. Con…
An assessment of the pulsar outer gap model. I: Assumptions, uncertainties, and implications for the gap size and the accelerating field
Daniele Viganò, Diego F. Torres, Kouichi Hirotani +1
The popular outer gap model of magnetospheric emission from pulsars has been widely applied to explain the properties observed in -rays. However, its quantitative predictions re…
Overview of the SDSS-IV MaNGA Survey: Mapping Nearby Galaxies at Apache Point Observatory
Kevin Bundy, Matthew A. Bershady, David R. Law +65
We present an overview of a new integral field spectroscopic survey called MaNGA (Mapping Nearby Galaxies at Apache Point Observatory), one of three core programs in the fourth-gen…
An updated estimate of the number of Jupiter-family comets using a simple fading law
R. Brasser, J. -H. Wang
It has long been hypothesised that the Jupiter-family comets (JFCs) come from the scattered disc, an unstable planetesimal population beyond Neptune. This viewpoint has been widely…
An assessment of the pulsar outer gap model. II: Implications for the predicted -ray spectra
Daniele Viganò, Diego F. Torres, Kouichi Hirotani +1
One of the most important predictions of any gap model for pulsar magnetospheres is the predicted -ray spectra. In the outer gap model, the properties of the synchro-curvature r…
HST Images Reveal Dramatic Changes in the Core of IRC+10216
Hyosun Kim, Ho-Gyu Lee, Nicolas Mauron +1
IRC+10216 is the nearest carbon star with a very high mass-loss rate. The existence of a binary companion has been hinted by indirect observational evidence, such as the bipolar mo…
Constraining the galaxy mass content in the core of A383 using velocity dispersion measurements for individual cluster members
A. Monna, S. Seitz, A. Zitrin +14
We use velocity dispersion measurements of 21 individual cluster members in the core of Abell 383, obtained with MMT Hectospec, to separate the galaxy and the smooth dark halo (DH)…
A carefully characterised and tracked Trans-Neptunian survey, the size-distribution of the Plutinos and the number of Neptunian Trojans
Mike Alexandersen, Brett Gladman, J. J. Kavelaars +3
The Trans-Neptunian Objects (TNOs) may preserve evidence of planet building in their orbital and size-distributions. While all populations show steep size-distributions for large o…
