This research is a library research that uses data in the form of books, laws, articles, journals and other literature related to the title, while the technique and data collection is by collecting various ideas, theories and concepts of various literature that are centered on the process of comparison between the evidence or other laws. The results of the study concluded that the ruling of the Constitutional Court against the position of the ad hoc judge is appropriate because it gives the same position on a different matter precisely caused injustice. In addition to having the authority to check, prosecute, and break the criminal corruption, adhoc judges also have the authority to examine the criminal case of money laundering that the original criminal act is a corruption crime. So here corruption as the original criminal act is often referred to as predicate crimes. It is no less important that the role and authority of the adhoc judge specialising in the association of article 6 letter c The authority of the Court of Law to handle a strict follow-up in another law is determined as a corruption criminal act
ВоспоминаниябританскогожурналистаМ.Ф.Прайсао1917годевРоссии
Authors: Sotnikova A.A. 
Published: September 2019

Книга известного британского журналиста Моргана Прайса, появившаяся в продаже в Англии в 1921 году, преследовала несколько основных целей. Вопервых, автор рассказал о своей работе в Российской империи во время ее революционного превращения в демократическое общество. Прайс не только высказал свое отношение к революции, ее лидерам и их противникам, но и зафиксировал ход реформ, представив их как постепенно поэтапные и многофункциональные. Вовторых, автор показывает свое сочувствие революции, народу, который после долгих лет рабства высказался за свои права и свободы. Изображая действия простых крепостных, солдат и рабочих, Прайс показывает их, а не их вождей, как творцов революции. Кроме того, Прайс предлагает уникальное портфолио по всем политическим лидерам революционной России, подробно описывая их внешность, манеры и поведение, записав их во время официального выступления. Эта книга сыграла важную роль в формировании отношения британского общества к переменам в России. Это помогло устранить неверие и оценить русскую революцию как типичный ход политических изменений, которые в определенный момент происходили во всех европейских странах. Прайс М. П. мои воспоминания о русской революции. Лондон, 1921 год.Р. 179. Пер. с англ. О.В. Кузнецовой.The book by the wellknown British journalist Morgan Price, which appeared to be sold in England in 1921, had several main goals. First, the author told about his job in the Russian Empire during its revolutionary transformation into a democratic society. Price not only stated his attitude towards the revolution, its leaders and their opponents, but also recorded the course of the reforms, presenting them as gradually staged and multifunctional. Secondly, the author reveals his sympathy to the revolution, the people, who after long years of slavery has spoken up for their rights and freedoms. Depicting the actions of simple serfs, soldiers and workers, Price shows them, not their leaders, as revolution creators. Moreover Price offers a unique portfolio on all the political leaders of the revolutionary Russia, depicting in details their appearance, manners and behavior, having recorded them while officially speaking. This book played an important role in forging the attitude of British society towards the changes in Russia. It helped to eliminate misbeliefs and to estimate the Russian Revolution as a typical course of political changes, which at a certain moment took place in all European countries. Price
America's Next Literary Foil: Deconstructing the Orientalized Body of the Other in Miranda Kenneally's Coming Up for Air.
Authors: Riestra-Camacho Rocio 
Published: September 2019

El objetivo de este artículo es examinar el Orientalismo como mecanismo literario de caracterización en la novela juvenil deportiva contemporánea norteamericana Coming Up for Air (2017), escrita por Miranda Kenneally. En ella se relata la transición de Maggie King a una universidad deportiva de natación en los Estados Unidos. El análisis se centrará, sin embargo, en Roxy Coulter, el personaje antagónico de Maggie. Dada su presentación como personaje exótico y erotizado, Roxy representa al personaje a través del cual se puede rastrear la presencia del motivo orientalista en la literatura actual juvenil. En ella, el público lector busca sentirse identificado con el protagonista y la alterización del resto de personajes puede contribuir a ello. De tal manera, se tratará de demostrar que la caracterización de la antagonista como personaje contrapunto y orientalizado supone un panorama de identificación pro-estadounidense basado en una codificación nacionalista, etnocéntrica y de género.
K2-146: Discovery of Planet c, Precise Masses from Transit Timing, and Observed Precession
Authors: Hamann Aaron , Montet Benjamin T. , Fabrycky Daniel C. , Agol Eric , Kruse Ethan 
Published: September 2019

Abstract
K2-146 is a mid-M dwarf (M
⋆ = 0.331 ± 0.009M
⊙; R
⋆ = 0.330 ± 0.010R
⊙), observed in Campaigns 5, 16, and 18 of the K2 mission. In Campaign 5 data, a single planet was discovered with an orbital period of 2.6 days and large transit timing variations due to an unknown perturber. Here, we analyze data from Campaigns 16 and 18, detecting the transits of a second planet, c, with an orbital period of 4.0 days, librating in a 3:2 resonance with planet b. Large, anticorrelated timing variations of both planets exist due to their resonant perturbations. The planets have a mutual inclination of 2.°40 ± 0.°25, which torqued planet c more closely into our line of sight. Planet c was grazing in Campaign 5 and thus missed in previous searches; it is fully transiting in Campaigns 16 and 18, and its transit depth is three times larger. We improve the stellar properties using data from Gaia DR2, and use dynamical fits to find that both planets are sub-Neptunes: their masses are 5.77 ± 0.18 and 7.50 ± 0.23M
⊕, and their radii are 2.04 ± 0.06 and 2.19 ± 0.07 R
⊕, respectively. These mass constraints set the precision record for small exoplanets (a few gas giants have comparable relative precision). These planets lie in the photoevaporation valley when viewed in Radius–Period space, but due to the low-luminosity M-dwarf host star, they lie among the atmosphere-bearing planets when viewed in Radius–Irradiation space. This, along with their densities being 60–80% that of Earth, suggests that they may both have retained a substantial gaseous envelope.

Abstract
We use published models of the early solar system evolution with a slow, long-range and grainy migration of Neptune to predict the orbital element distributions and the number of modern-day Centaurs. The model distributions are biased by the Outer Solar System Origins Survey (OSSOS) simulator and compared with the OSSOS Centaur detections. We find an excellent match to the observed orbital distribution, including the wide range of orbital inclinations which was the most troublesome characteristic to fit in previous models. A dynamical model, in which the original population of outer disk planetesimals was calibrated from Jupiter trojans, is used to predict that OSSOS should detect 11 ± 4 Centaurs with semimajor axes of a < 30 au, perihelion distances of q > 7.5 au, and diameter of D > 10 km (absolute magnitude H

r
< 13.7 for a 6% albedo). This is consistent with 15 actual OSSOS Centaur detections with H

r
< 13.7. The population of Centaurs is estimated to be 21,000 ± 8000 for D > 10 km. The inner scattered disk at 50 < a < 200 au should contain (2.0 ± 0.8) × 107
D > 10 km bodies and the Oort cloud should contain (5.0 ± 1.9) × 108
D > 10 km comets. Population estimates for different diameter cutoffs can be obtained from the size distribution of Jupiter trojans (N(>D) ∝ D
−2.1 for 5 < D < 100 km). We discuss model predictions for the Large Synoptic Survey Telescope observations of Centaurs.
New Star Observations with NuSTAR: Flares from Young Stellar Objects in the ρ Ophiuchi Cloud Complex in Hard X-Rays
Authors: Vievering Juliana T. , Glesener Lindsay , Grefenstette Brian W. , Smith David M. 
Published: September 2019

Abstract
We study the structure and dynamics of extreme flaring events on young stellar objects (YSOs) observed in hard X-rays by the Nuclear Spectroscopic Telescope Array (NuSTAR). During 2015 and 2016, NuSTAR made three observations of the star-forming region ρ Ophiuchi, each with an exposure ∼50 ks. NuSTAR offers unprecedented sensitivity above ∼7 keV, making this data set the first of its kind. Through improved coverage of hard X-rays, it is finally possible to directly measure the high-energy thermal continuum for hot plasmas and to sensitively search for evidence of nonthermal emission from YSO flares. During these observations, multiple flares were observed, and spectral and timing analyses were performed on three of the brightest flares. By fitting an optically thin thermal plasma model to each of these events, we found flare plasma heated to high temperatures (∼40−80 MK) and determined that these events are ∼1000 times brighter than the brightest flares observed on the Sun. Two of the studied flares showed excess emission at 6.4 keV, and this excess may be attributable to iron fluorescence in the circumstellar disk. No clear evidence for a nonthermal component was observed, but upper limits on nonthermal emission allow for enough nonthermal energy to account for the estimated thermal energy in the flare on protostar IRS 43, which is consistent with the standard model for solar and stellar flares.

Abstract
We report our observations of HSC16aayt (SN 2016jiu), which was discovered by the Subaru/Hyper Suprime-Cam (HSC) transient survey conducted as part of the Subaru Strategic Program. It shows very slow photometric evolution and its rise time is more than 100 days. The optical magnitude change in 400 days remains within 0.6 mag. Spectra of HSC16aayt show a strong narrow emission line and we classify it as a Type IIn supernova. The redshift of HSC16aayt is 0.6814 ± 0.0002 from the spectra. Its host galaxy center is at 5 kpc from the supernova location and HSC16aayt might be another example of isolated Type IIn supernovae, although the possible existence of underlying star-forming activity of the host galaxy at the supernova location is not excluded.

Published: September 2019

Abstract
The optical and ultraviolet broadband photometric and spectroscopic observations of the Type II supernova (SN) 2016gfy are presented. The V-band light curve (LC) shows a distinct plateau phase with a slope of s
2 ∼ 0.12 mag (100 day)−1 and a duration of 90 ± 5 days. Detailed analysis of SN 2016gfy provided a mean 56Ni mass of 0.033 ± 0.003 M
⊙, a progenitor radius of ∼350–700 R
⊙, a progenitor mass of ∼12–15 M
⊙, and an explosion energy of (0.9–1.4) × 1051 erg s−1. The P-Cygni profile of Hα in the early-phase spectra (∼11–21 days) shows a boxy emission. Assuming that this profile arises from the interaction of the SN ejecta with the pre-existing circumstellar material (CSM), it is inferred that the progenitor underwent a recent episode (30–80 yr prior to the explosion) of enhanced mass loss. Numerical modeling suggests that the early LC peak is reproduced better with an existing CSM of 0.15 M
⊙ spread out to ∼70 au. A late-plateau bump is seen in the VRI LCs during ∼50–95 days. This bump is explained as a result of the CSM interaction and/or partial mixing of radioactive 56Ni in the SN ejecta. Using strong-line diagnostics, a subsolar oxygen abundance is estimated for the supernova H ii region (12 + log(O/H) = 8.50 ± 0.11), indicating an average metallicity for the host of an SN II. A star formation rate of ∼8.5 M
⊙ yr−1 is estimated for NGC 2276 using the archival GALEX FUV data.
Dynamics of Multiple Bodies in a Corotation Resonance: Conserved Quantities and Relevance to Ring Arcs
Authors: A’Hearn Joseph A. , Hedman Matthew M. , El Moutamid Maryame 
Published: September 2019

Abstract
The interactions among objects in a mean motion resonance are important for the orbital evolution of satellites and rings, especially Saturn’s ring arcs and associated moons. In this work, we examine interactions among massive bodies in the same corotation eccentricity resonance site that affect the orbital evolution of those bodies using numerical simulations. During these simulations, the bodies exchange angular momentum and energy during close encounters, altering their orbits. This energy exchange, however, does not mean that one body necessarily moves closer to exact corotation when the other moves away from it. Indeed, if one object moves toward one of these sites, the other object is equally likely to move toward or away from it. This happens because the timescale of these close encounters is short compared to the synodic period between these particles and the secondary mass (i.e., the timescale where corotation sites can be treated as potential maxima). Because the timescale of a gravitational encounter is comparable to the timescale of a collision, we could expect energy to be exchanged in a similar way for collisional interactions. In that case, these findings could be relevant for denser systems like the arcs in Neptune’s Adams ring and how they can be maintained in the face of frequent inelastic collisions.
Measuring the Obscuring Column of a Disk Megamaser AGN in a Nearby Merger

Published: September 2019

Abstract
Active galactic nuclei (AGNs) hosting disk water megamasers are well known to be obscured by large amounts of gas, likely due to the presence along the line of sight of an almost edge-on disky structure orbiting the supermassive black hole. Correcting for the high obscuration is crucial to infer parameters intrinsic to the source, like its luminosity. We present a broadband X-ray spectral analysis of a water megamaser AGN in an early merger (NGC 5765B), combining Chandra and NuSTAR data. NGC 5765B is highly Compton-thick and reflection-dominated, following the general trend among disk megamasers. Combining the exquisite black hole mass from masers with our X-ray spectroscopy, the Eddington ratio of the megamaser is estimated to be in the 2%–14% range, and its robustness is confirmed through SED fitting.
Impact of Accretion Flow Dynamics on Gas-dynamical Black Hole Mass Estimates
Authors: Jeter Britton , Broderick Avery E. , McNamara B. R. 
Published: September 2019

Abstract
At low redshift, the majority of supermassive black hole (SMBH) mass estimates are obtained from modeling stellar kinematics or ionized gas dynamics in the vicinity of the galaxy nucleus. For large early type galaxies, stellar kinematics models predict higher masses than gas-dynamical models. In the case of M87, this discrepancy is larger than 2σ. Critical to gas-dynamical modeling is the assumed underlying dynamical state of the gas: that it lies on circular Keplerian orbits, potentially with some additional turbulent pressure support. This is inconsistent with models of the gas flow about low-accretion-rate SMBHs and at odds with observations of the Galactic Center. We present a simple model for non-Keplerian gas disks and explore their implications for SMBH mass measurements. We show that a larger central black hole with gas experiencing small amounts of sub-Keplerian motion can produce velocity curves similar to models that just contain circular Keplerian motions and a lower black hole mass. However, these non-Keplerian models are distinguishable from low-mass Keplerian models primarily through measurements of the velocity dispersion, wherein non-Keplerian models produce higher and narrower peak dispersions. Away from the galaxy center, but still within the circumnuclear gas disk, non-Keplerian models also become distinguishable from Keplerian models via a shift in the velocity curve. The velocity model presented in this paper is capable of resolving the discrepancy between the ionized gas dynamics and stellar kinematics mass estimates, and is applicable to gas-dynamical mass estimates of SMBHs in general.

Abstract
We use the one-dimensional TRISTAN-MP particle-in-cell code to model the nonlinear evolution of the whistler heat flux instability (WHFI) that was proposed by Gary et al. and Gary & Li to regulate the electron heat flux in the solar wind and astrophysical plasmas. The simulations are initialized with electron velocity distribution functions typical for the solar wind. We perform a set of simulations at various initial values of the electron heat flux and β

Spectral Magnetic Helicity of Solar Active Regions between 2006 and 2017
Authors: Gosain Sanjay , Brandenburg Axel 
Published: September 2019

Abstract
We compute magnetic helicity and energy spectra from about 2485 patches of about 100 Mm side length on the solar surface using data from Hinode during 2006–2017. An extensive database is assembled where we list the magnetic energy and helicity, large- and small-scale magnetic helicity, mean current helicity density, fractional magnetic helicity, and correlation length along with the Hinode map identification number (MapID), as well as the Carrington latitude and longitude for each MapID. While there are departures from the hemispheric sign rule for magnetic and current helicities, the weak trend reported here is in agreement with the previous results. This is argued to be a physical effect associated with the dominance of individual active regions that contribute more strongly in the better-resolved Hinode maps. In comparison with earlier work, the typical correlation length is found to be 6–

Abstract
We have obtained Hubble Space Telescope STIS and NICMOS and Gemini/GPI scattered-light images of the HD 191089 debris disk. We identify two spatial components: a ring resembling the Kuiper Belt in radial extent (FWHM ∼ 25 au, centered at ∼46 au) and a halo extending to ∼640 au. We find that the halo is significantly bluer than the ring, consistent with the scenario that the ring serves as the “birth ring” for the smaller dust in the halo. We measure the scattering phase functions in the 30°–150° scattering-angle range and find that the halo dust is more forward- and backward-scattering than the ring dust. We measure a surface density power-law index of −0.68 ± 0.04 for the halo, which indicates the slowdown of the radial outward motion of the dust. Using radiative transfer modeling, we attempt to simultaneously reproduce the (visible) total and (near-infrared) polarized intensity images of the birth ring. Our modeling leads to mutually inconsistent results, indicating that more complex models, such as the inclusion of more realistic aggregate particles, are needed.
