ABSTRACT
We report the results of our observing campaign on GRB 140903A, a nearby (z = 0.351) short-duration (T
90 ∼ 0.3 s) gamma-ray burst discovered by Swift. We monitored the X-ray afterglow with Chandra up to 15 days after the burst and detected a steeper decay of the X-ray flux after t

j
≈ 1 day. Continued monitoring at optical and radio wavelengths showed a similar decay in flux at nearly the same time, and we interpret it as evidence of a narrowly collimated jet. By using the standard fireball model to describe the afterglow evolution, we derive a jet opening angle θ

j
≈ 5° and a collimation-corrected total energy release E ≈ 2

erg. We further discuss the nature of the GRB progenitor system. Three main lines disfavor a massive star progenitor: the properties of the prompt gamma-ray emission, the age and low star formation rate of the host galaxy, and the lack of a bright supernova. We conclude that this event likely originated from a compact binary merger.
QUASARS AS A TRACER OF LARGE-SCALE STRUCTURES IN THE DISTANT UNIVERSE

Published: August 2016

ABSTRACT
We study the dependence of the number density and properties of quasars on the background galaxy density using the currently largest spectroscopic data sets of quasars and galaxies. We construct a galaxy number density field smoothed over the variable smoothing scale of between approximately 10 and 20 h
−1 Mpc over the redshift range 0.46 < z < 0.59 using the Sloan Digital Sky Survey (SDSS) Data Release 12 (DR12) Constant MASS galaxies. The quasar sample is prepared from the SDSS-I/II DR7. We examine the correlation of incidence of quasars with the large-scale background density and the dependence of quasar properties such as bolometric luminosity, black hole mass, and Eddington ratio on the large-scale density. We find a monotonic correlation between the quasar number density and large-scale galaxy number density, which is fitted well with a power-law relation,

. We detect weak dependences of quasar properties on the large-scale density such as a positive correlation between black hole mass and density, and a negative correlation between luminosity and density. We discuss the possibility of using quasars as a tracer of large-scale structures at high redshifts, which may be useful for studies of the growth of structures in the high-redshift universe.
EVOLUTION OF DWARF SPHEROIDAL SATELLITES IN THE COMMON SURFACE-DENSITY DARK HALOS
Authors: Okayasu Yusuke , Chiba Masashi 
Published: August 2016

ABSTRACT
We investigate the growth histories of dark matter halos associated with dwarf satellites in Local Group galaxies and the resultant evolution of the baryonic component. Our model is based on the recently proposed property that the mean surface density of a dark halo inside a radius at maximum circular velocity

is universal over a large range of

. Given that a surface density of 20 M
⊙ pc−2 well explains dwarf satellites in the Milky Way and Andromeda, we find that the evolution of the dark halo in this common surface-density scale is characterized by the rapid increase of the halo mass assembled by the redshift

of the tidal truncation by its host halo, at early epochs of

or

km s−1. This mass growth of the halo is slow at lower

or larger

. Taking into account the baryon content in this dark halo evolution, under the influence of the ionizing background radiation, we find that the dwarf satellites are divided into roughly two families: those with

km s−1 having high star formation efficiency and those with larger

having less efficient star formation. This semianalytical model is in agreement with the high-resolution numerical simulation for galaxy formation and with the observed star formation histories for Fornax and Leo II. This suggests that the evolution of a dark halo may play a key role in understanding star formation histories in dwarf satellites.

ABSTRACT
We present CO(1–0) observations of objects within the Shocked POststarburst Galaxy Survey taken with the Institut de Radioastronomie Millimétrique 30 m single dish and the Combined Array for Research for Millimeter Astronomy interferometer. Shocked poststarburst galaxies (SPOGs) represent a transitioning population of galaxies, with deep Balmer absorption

, consistent with an intermediate-age (A-star) stellar population, and ionized gas line ratios inconsistent with pure star formation. The CO(1–0) subsample was selected from SPOGs detected by the Wide-field Infrared Survey Explorer with 22 μm flux detected at a signal-to-noise ratio (S/N) > 3. Of the 52 objects observed in CO(1–0), 47 are detected with S/N > 3. A large fraction (37%–46% ± 7%) of our CO-SPOG sample were visually classified as morphologically disrupted. The H2 masses detected were between

, consistent with the gas masses found in normal galaxies, though approximately an order of magnitude larger than the range seen in poststarburst galaxies. When comparing the 22 μm and CO(1–0) fluxes, SPOGs diverge from the normal star-forming relation, having 22 μm fluxes in excess of the relation by a factor of

, suggestive of the presence of active galactic nuclei (AGNs). The Na i D characteristics of CO-SPOGs show that it is likely that many of these objects host interstellar winds. Objects with large Na i D enhancements also tend to emit in the radio, suggesting possible AGN driving of neutral winds.

ABSTRACT
Giant molecular clouds contain supersonic turbulence that can locally heat small fractions of gas to over 100 K. We run shock models for low-velocity, C-type shocks propagating into gas with densities between 103 and 105 cm−3 and find that CO lines are the most important cooling lines. Comparison to photodissociation region (PDR) models indicates that mid-J CO lines (J = 8

7 and higher) should be dominated by emission from shocked gas. In Papers I and II we presented CO J = 3

2, 8

7, and 9

8 observations toward four primarily quiescent clumps within infrared dark clouds. Here we fit PDR models to the combined spectral line energy distributions and show that the PDR models that best fit the low-J CO emission underpredict the mid-J CO emission by orders of magnitude, strongly hinting at a hot gas component within these clumps. The low-J CO data clearly show that the integrated intensities of both the CO J = 8

7 and 9

8 lines are anomalously high, such that the line ratio can be used to characterize the hot gas component. Shock models are reasonably consistent with the observed mid-J CO emission, with models with densities near

cm−3 providing the best agreement. Where this mid-J CO is detected, the mean volume filling factor of the hot gas is 0.1%. Much of the observed mid-J CO emission, however, is also associated with known protostars and may be due to protostellar feedback.
A WISE CENSUS OF YOUNG STELLAR OBJECTS IN CANIS MAJOR
Authors: Fischer William J. , Padgett Deborah L. , Stapelfeldt Karl L. , Sewiło Marta 
Published: August 2016

ABSTRACT
With the Wide-field Infrared Survey Explorer (WISE), we searched for young stellar objects (YSOs) in a 100 deg2 region centered on the lightly studied Canis Major star-forming region. Applying stringent magnitude cuts to exclude the majority of extragalactic contaminants, we find 144 Class I candidates and 335 Class II candidates. The sensitivity to Class II candidates is limited by their faintness at the distance to Canis Major (assumed as 1000 pc). More than half the candidates (53%) are found in 16 groups of more than four members, including four groups with more than 25 members each. The ratio of Class II to Class I objects, N
II/N
I, varies from 0.4 to 8.3 in just the largest four groups. We compare our results to those obtainable with combined Two Micron All Sky Survey and post-cryogenic Spitzer Space Telescope data; the latter approach recovers missing Class II sources. Via a comparison to protostars characterized with the Herschel Space Observatory, we propose new WISE color criteria for flat-spectrum and Class 0 protostars, finding 80 and 7 of these, respectively. The distribution of YSOs in CMa OB1 is consistent with supernova-induced star formation, although the diverse N
II/N
I ratios are unexpected if this parameter traces age and the YSOs are due to the same supernova. Less massive clouds feature larger N
II/N
I ratios, suggesting that initial conditions play a role in determining this quantity.
THE INFLOW SIGNATURE TOWARD DIFFERENT EVOLUTIONARY PHASES OF MASSIVE STAR FORMATION
Authors: Jin Miwha , Lee Jeong-Eun , Kim Kee-Tae , Evans II Neal J. 
Published: August 2016

ABSTRACT
We analyze both HCN J = 1–0 and HNC J = 1–0 line profiles to study the inflow motions in different evolutionary stages of massive star formation: 54 infrared dark clouds (IRDCs), 69 high-mass protostellar objects (HMPOs), and 54 ultra-compact H ii regions (UCHIIs). Inflow asymmetry in the HCN spectra seems to be prevalent throughout all the three evolutionary phases, with IRDCs showing the largest excess in the blue profile. In the case of the HNC spectra, the prevalence of blue sources does not appear, apart from for IRDCs. We suggest that this line is not appropriate to trace the inflow motion in the evolved stages of massive star formation, because the abundance of HNC decreases at high temperatures. This result highlights the importance of considering chemistry in dynamics studies of massive star-forming regions. The fact that the IRDCs show the highest blue excess in both transitions indicates that the most active inflow occurs in the early phase of star formation, i.e., in the IRDC phase rather than in the later phases. However, mass is still inflowing onto some UCHIIs. We also find that the absorption dips of the HNC spectra in six out of seven blue sources are redshifted relative to their systemic velocities. These redshifted absorption dips may indicate global collapse candidates, although mapping observations with better resolution are needed to examine this feature in more detail.
AN EXTENSION OF THE ATHENA++ CODE FRAMEWORK FOR GRMHD BASED ON ADVANCED RIEMANN SOLVERS AND STAGGERED-MESH CONSTRAINED TRANSPORT
Authors: White Christopher J. , Stone James M. , Gammie Charles F. 
Published: August 2016

ABSTRACT
We present a new general relativistic magnetohydrodynamics (GRMHD) code integrated into the Athena++ framework. Improving upon the techniques used in most GRMHD codes, ours allows the use of advanced, less diffusive Riemann solvers, in particular HLLC and HLLD. We also employ a staggered-mesh constrained transport algorithm suited for curvilinear coordinate systems in order to maintain the divergence-free constraint of the magnetic field. Our code is designed to work with arbitrary stationary spacetimes in one, two, or three dimensions, and we demonstrate its reliability through a number of tests. We also report on its promising performance and scalability.

ABSTRACT
We provide a set of stellar evolution and nucleosynthesis calculations that applies established physics assumptions simultaneously to low- and intermediate-mass and massive star models. Our goal is to provide an internally consistent and comprehensive nuclear production and yield database for applications in areas such as presolar grain studies. Our non-rotating models assume convective boundary mixing (CBM) where it has been adopted before. We include 8 (12) initial masses for Z = 0.01 (0.02). Models are followed either until the end of the asymptotic giant branch phase or the end of Si burning, complemented by simple analytic core-collapse supernova (SN) models with two options for fallback and shock velocities. The explosions show which pre-SN yields will most strongly be effected by the explosive nucleosynthesis. We discuss how these two explosion parameters impact the light elements and the s and p process. For low- and intermediate-mass models, our stellar yields from H to Bi include the effect of CBM at the He-intershell boundaries and the stellar evolution feedback of the mixing process that produces the

pocket. All post-processing nucleosynthesis calculations use the same nuclear reaction rate network and nuclear physics input. We provide a discussion of the nuclear production across the entire mass range organized by element group. The entirety of our stellar nucleosynthesis profile and time evolution output are available electronically, and tools to explore the data on the NuGrid VOspace hosted by the Canadian Astronomical Data Centre are introduced.

ABSTRACT
Using the UltraVISTA DR1 and 3D-HST catalogs, we construct a stellar-mass-complete sample, unique for its combination of surveyed volume and depth, to study the evolution of the fractions of quiescent galaxies, moderately unobscured star-forming galaxies, and dusty star-forming galaxies as a function of stellar mass over the redshift interval 0.2 ≤ z ≤ 3.0. We show that the role of dusty star-forming galaxies within the overall galaxy population becomes more important with increasing stellar mass and grows rapidly with increasing redshift. Specifically, dusty star-forming galaxies dominate the galaxy population with

at z ≳ 2. The ratio of dusty and non-dusty star-forming galaxies as a function of stellar mass changes little with redshift. Dusty star-forming galaxies dominate the star-forming population at

Evaluer l’effet local d’une innovation : une application au marché du poisson français
Authors: Gobillon Laurent , Wolff François-Charles 
Published: August 2016

Cet article propose une évaluation de l’effet de l’introduction d’une nouvelle technique de pêche aux Sables d’Olonne sur la qualité des poissons pêchés à partir de la méthode des contrôles synthétiques et de l’estimation de modèles à facteurs. Les estimations sont menées sur des données agrégées des criées françaises sur la période 2009-2012. Notre estimateur préféré de l’effet de l’innovation à composition constante des espèces pêchées est obtenu avec le modèle à facteurs et correspond à un accroissement de 16,9 % de la proportion de poissons présentant la meilleure qualité. La méthode des contrôles synthétiques conduit à un effet moindre de l’innovation (8,3 %), mais elle repose sur une interpolation de la criée des Sables d’Olonne à partir des criées de contrôle qui est assez approximative.

Abstract
Antisynthetase syndrome (aSS) is characterized by the association of interstitial lung disease and myositis with anti–tRNA synthetase autoantibodies. Immune mechanisms leading to aSS could be initiated in the lungs, but the role of NK cells has not yet been studied. Both extensive NK cell phenotype and functions were compared between 33 patients and 26 controls. Direct and redirected polyfunctionality assays (degranulation and intracellular production of TNF-α and IFN-γ) were performed spontaneously or after IL-12 plus IL-18 stimulation in the presence of K562 or P815 target cells, respectively. NK cells from inactive patients showed normal phenotype, whereas active aSS revealed a differentiated NK cell profile, as indicated by increased CD57 and Ig-like transcript 2 and an inability to produce IFN-γ (p = 0.002) compared with controls. Importantly, active aSS was more specifically associated with a significant NKp30 decrease (p = 0.009), although levels of mRNA and intracellular protein were similar in aSS and healthy controls. This NKp30 decrease was strongly correlated with reduced NK cell polyfunctionality in both direct and redirected killing assays with anti-NKp30 Abs (p = 0.009 and p = 0.03, respectively), confirming its important impact in aSS. Histological studies revealed massive infiltrations of NK cells inside the lungs of aSS patients (148 versus 11/mm2). Taken together, these data suggest that NK cells and NKp30 could play a role in aSS pathogenesis.
Design It Yourself Surabaya: Reflective Notes on Designing a Festival
Authors: Azali Kathleen , Budiman Andriew 
Published: August 2016

As a relatively new, imported word, the term desain (design) in Indonesian is still mostly understood within its relations to three common academic fields—graphic, interior, and product design—and thus tends to be viewed as belonging to the ‘merely’ visual. While local cultural events and festivals have proliferated in Indonesia, the scope for a conference or a festival that explicitly address design therefore tends to be rather limited. This is not to say that design exhibitions and festivals do not exist. In fact, they have flourished in the country, particularly among university students, reflecting the growth of university design programs and schools to meet contemporary demand. Yet visual-based, market-led development has not been accompanied by institutional development in research and outreach (in the form of dialogues or critical publications), particularly ones that connect that development across different fields. Attaching the word desain to an event in Indonesia invariably means it is associated with either design student exhibitions, or an industrial expo showcasing printers or interior furnitures. This curated piece emerges as our reflection on designing—cobbling up, and calibrating—a design conference-festival from Surabaya, East Java, Indonesia in light of the national context in which desain is received and made meaningful.
Batik of Batang - A Design Story
Authors: Dunn Jessica Lea 
Published: August 2016

During my time living in Central Java, Indonesia, I stayed in the family home of one of my Indonesian friends on multiple occasions. In my friend’s village, located in the district of Batang, along the north coast of Java, west of Semarang city, almost every woman has the ability to produce exquisitely detailed hand-drawn batik fabric. A walk up a lane or a peep into a neighbour’s house will often reveal a solo entrepreneur contributing their wares to a dynamic cottage industry. However, the lifestyle is hard and the reward almost not enough to justify the patience and hours required to produce fine batik cloth.

Multilinguïsation des systèmes traitant des sous-langages
Authors: Hajlaoui Najeh 
Published: August 2016

Dans le cadre de nos travaux sur la multilinguïsation ou « portage linguistique » des services de gestion de contenu traitant des énoncés spontanés en langue naturelle, nous avons dégagé trois méthodes de portage possibles d’une langue L1 vers une nouvelle langue L2, et les avons appliquées sur des cas de systèmes de e-commerce. Le portage par traduction statistique, une de ces trois méthodes, a donné de très bonnes performances, et ce, avec un corpus d’apprentissage très petit (moins de 10 000 mots). Cela prouve que, dans le cas de sous-langages très petits, la traduction statistique peut être de qualité suffisante en partant de corpus 100 à 500 fois moins grands que pour de la langue générale.
