Peran Orang Tua Terhadap Anak Perspektif Pendidikan Islam
Authors: Rachman Lutfi 
Published: April 2020

Pada umunya setiap orang merasa mengerti tentang apa pendidikan itu. Akan tetapi apabila kepadanya ditanya lebih jauh mengenai arti yang esensial, mengenai dasar dan tujuan serta mengenai persoalan lain tentang pendidikan itu baru ia menyadari bahwa pengetahuannya tentang itu hanya samat-samar saja.Persoalan mengenai pendidikan itu demikian luas dan dalam sehingga para ilmuwan memandangnya sebagai suatu bidang kajian khusus, sebagai suatu disiplin ilmu sendiri yang untuk pengkajiannya dan pendalamannya diperlukan suatu studi yang khusus pula. Karena pengertian pendidikan itu sendiri dapat kita temukan dari berbagai definisi. Tergantung dari sudut pandang mana kita akan mengkajinya, akan tetapi pada umumnya tiada yang berbeda pendapat bahwa pendidikan itu pada dasarnya merupakan suatu perbuatan atau tindakan yang di lakukan dengan maksud agar anak atau orang yang dihadapi itu akan meningkatkan pengetahuannya.Oleh karena itu peranan orang tua dalam membimbing anak-anaknya sangatlah penting.Pengaruh keluarga amat besar dalam pembentukan pondasi kepribadian anak. Keluarga yang gagal membentuk kepribadian anak biasanya adalah keluarga yang penuh dengan konflik atau tidak bahagia. Tugas berat para orang tua adalah meyakinkan fungsi keluarga mereka benar-benar aman, nyaman bagi anak-anak mereka. Rumah adalah surga bagi anak, dimana mereka dapat menjadi cerdas, sholeh, dan tentu saja tercukupi lahir dan bathinnya. Dengan demikian orang tua lebih mudah untuk mengawasi anaknya, langkah yang harus dilakukan adalah dengan menemaninya belajar, sehingga membantu kesulitan belajar sang anak, sehingga terciptalah hubungan yang harmonis antara orang tua dan anaknya. Dan orang tua hendaknya selalu memperhatiakan dan mengontrol akan perkembangan anaknya, dan memeperhatikan siapa teman bermainnya, serta memberikan motivasi belajar kepada anaknya, untuk bisa hidup mandiri.

Hubble Space Telescope Search for Activity in High-perihelion Objects
Authors: Li 李 Jing 京 , Jewitt David , Mutchler Max , Agarwal Jessica , Weaver Harold 
Published: April 2020

Abstract
Solar system objects with perihelia beyond the orbit of Jupiter (q > 5 au) are too cold for water ice to generate an appreciable coma via sublimation. Despite this, numerous high-perihelion objects (HPOs) including many comets and recently escaped Kuiper Belt objects (Centaurs) are observed to be active out at least to the orbit of Saturn (q ∼ 10 au). Peak equilibrium temperatures at 10 au (∼125 K), while far too low to sublimate water ice, are sufficient to sublimate supervolatiles such as CO and CO2 ice. Temperatures at 10 au are also high enough to trigger the rapid crystallization of exposed amorphous ice, thus constituting another possible driver of distant activity. While supervolatile ices can sublimate strongly (as

) to at least Kuiper Belt (30 au) distances, crystallization is an exponential function of temperature that cannot be sustained much beyond ∼10 au. The heliocentric dependence of the activity thus suggests an observational test. If activity in high-perihelion objects is triggered by crystallization, then no examples of activity should be found with perihelia of q ≫ 10 au. If, on the other hand, activity is due to free sublimation of exposed supervolatile ices, or another cause, then distant activity might be detected. We obtained sensitive, high-resolution Hubble Space Telescope observations of HPOs to search for activity beyond the crystallization zone. No examples of activity were detected in 53 objects with q > 15 au, consistent with the crystallization trigger hypothesis. However, sensitivity limits are such that we cannot reject the alternative hypothesis that mass loss is driven by the sublimation of supervolatile ices. We also searched for binary companions in our sample, finding none and setting an empirical 3σ limit to the binary fraction of <8%.
A Scenario for Ultradiffuse Satellite Galaxies with Low Velocity Dispersions: The Case of [KKS 2000]04
Authors: Nusser Adi 
Published: April 2020

Abstract
A scenario for achieving a low velocity dispersion for the galaxy [KKS 2000]04 (aka NGC 1052-DF2) and similar galaxies is presented. A progenitor halo corresponding to a z = 0 halo of mass

and a low concentration parameter (but consistent with cosmological simulations) infalls onto a Milky Way–size host at early times. Substantial removal of cold gas from the inner regions by supernova feedback and ram pressure, assisted by tidal stripping of the dark matter in the outer regions, leads to a substantial reduction of the velocity dispersion of stars within one effective radius. In this framework, the observed stellar content of [KKS 2000]04 is associated with a progenitor mass close to that inferred from the global stellar-to-halo-mass ratio. As far as the implications of kinematics are concerned, even if at a ∼20 Mpc distance, it is argued that [KKS 2000]04 is no more peculiar than numerous early type galaxies with seemingly little total dark-matter content.

Abstract
The intergalactic medium (IGM) at z ∼ 5 to 6 is largely ionized, and yet the main source for the IGM ionization in the early universe is uncertain. Of the possible contributors are faint quasars with

, but their number density is poorly constrained at z ∼ 5. In this paper, we present our survey of faint quasars at z ∼ 5 in the European Large-Area Infrared Space Observatory Survey-North 1 (ELAIS-N1) field over a survey area of 6.51 deg2 and examine if such quasars can be the dominant source of the IGM ionization. We use the deep optical/near-infrared data of the ELAIS-N1 field as well as the additional medium-band observations to find z ∼ 5 quasars through a two-step approach using the broadband color selection, and spectral energy distribution fitting with the medium-band information included. Adopting Bayesian information criterion, we identify 10 promising quasar candidates. Spectra of three of the candidates are obtained, confirming all of them to be quasars at z ∼ 5 and supporting the reliability of the quasar selection. Using the promising candidates, we derive the z ∼ 5 quasar luminosity function at −26 ≲ M
1450 ≲ −23. The number density of faint z ∼ 5 quasars in the ELAIS-N1 field is consistent with several previous results that quasars are not the main contributors to the IGM-ionizing photons at z ∼ 5.
Leptonic or Hadronic Emission: The X-Ray Radiation Mechanism of Large-scale Jet Knots in 3C 273
Authors: Wang Zhen-Jie , Zhang Jin , Sun Xiao-Na , Liang En-Wei 
Published: April 2020

Abstract
A comprehensively theoretical analysis of the broadband spectral energy distributions (SEDs) of large-scale jet knots in 3C 273 is presented to reveal their X-ray radiation mechanism. We show that these SEDs cannot be explained with a single-electron population model when the Doppler boosting effect is either considered or not. By adding a more energetic electron (the leptonic model) or proton (the hadronic model) population, the SEDs of all knots are well represented. In the leptonic model, the electron population that contributes the X-ray emission is more energetic than the one responsible for the radio-optical emission by almost two orders of magnitude; the derived equipartition magnetic field strengths (B
eq) are ∼0.1 mG. In the hadronic model, protons with energy ∼20 PeV are required to interpret the observed X-rays; the B
eq values are several mG, larger than those in the leptonic model. Based on the fact that no resolved substructures are observed in these knots and the fast cooling time of the high-energy electrons does not easily explain the observed X-ray morphologies, we argue that the two distinct electron populations accelerated in these knots are unreasonable and their X-ray emission is attributed to the proton synchrotron radiation accelerated in these knots. In cases where these knots have relativistic motion toward the observer, the super-Eddington issue of the hadronic model can be avoided. Multiwavelength polarimetry and γ-ray observations with high resolution may be helpful to discriminate these models.
The Width, Density, and Outflow of Solar Coronal Streamers
Authors: Morgan Huw , Cook Anthony C. 
Published: April 2020

Abstract
Characterizing the large-scale structure and plasma properties of the inner corona is crucial to understanding the source and subsequent expansion of the solar wind and related space weather effects. Here, we apply a new coronal rotational tomography method, along with a method to narrow streamers and refine the density estimate, to COR2A/Solar Terrestrial Relations Observatory observations from a period near solar minimum and maximum, gaining density maps for heights between 4 and 8R
⊙. The coronal structure is highly radial at these heights, and the streamers are very narrow: in some regions, only a few degrees in width. The mean densities of streamers is almost identical between solar minimum and maximum. However, streamers at solar maximum contain around 50% more total mass due to their larger area. By assuming a constant mass flux, and constraints on proton flux measured by Parker Solar Probe (PSP), we estimate an outflow speed within solar minimum streamers of 50–120 kms−1 at 4R
⊙, increasing to 90–250 kms−1 at 8R
⊙. Accelerations of around 6 ms−2 are found for streamers at a height of 4R
⊙, decreasing with height. The solar maximum slow wind shows a higher acceleration to extended distances compared with solar minimum. To satisfy the solar wind speeds measured by PSP, there must be a mean residual acceleration of around 1–2 ms−2 between 8 and 40R
⊙. Several aspects of this study strongly suggest that the coronal streamer belt density is highly variable on small scales, and that the tomography can only reveal a local spatial and temporal average.

Published: April 2020

Abstract
We present a study of the evolution of the inner few astronomical units of protoplanetary disks around low-mass stars. We consider nearby stellar groups with ages spanning from 1 to 11 Myr, distributed into four age bins. Combining PANSTARSS photometry with spectral types, we derive the reddening consistently for each star, which we use (1) to measure the excess emission above the photosphere with a new indicator of IR excess and (2) to estimate the mass accretion rate (

as a constraint to fix the initial conditions and the viscosity parameter of viscous evolutionary models, we use approximate Bayesian modeling to infer the dust properties that produce the observed decrease of the IR excess with age, in the range between 4.5 and 24 μm. We calculate an extensive grid of irradiated disk models with a two-layered wall to emulate a curved dust inner edge and obtain the vertical structure consistent with the surface density predicted by viscous evolution. We find that the median dust depletion in the disk upper layers is

Black Hole Coagulation: Modeling Hierarchical Mergers in Black Hole Populations
Authors: Doctor Z. , Wysocki D. , O’Shaughnessy R. , Holz D. E. , Farr B. 
Published: April 2020

Abstract
Data from the Laser Interferometer Gravitational Wave Observatory (LIGO) and Virgo detectors have confirmed that stellar-mass black holes can merge within a Hubble time, leaving behind massive remnant black holes. In some astrophysical environments such as globular clusters and active galactic nucleus disks, it may be possible for these remnants to take part in further compact-object mergers, producing a population of hierarchically formed black holes. In this work, we present a parameterized framework for describing the population of binary black hole (BBH) mergers, while self-consistently accounting for hierarchical mergers. The framework casts black holes as particles in a box that can collide based on an effective cross section, but allows inputs from more detailed astrophysical simulations. Our approach is relevant to any population that is comprised of second- or higher-generation black holes, such as primordial black holes or dense cluster environments. We describe some possible inputs to this generic model and their effects on the black hole merger populations and use the model to perform Bayesian inference on the catalog of black holes from LIGO and Virgo’s first two observing runs. We find that models with a high rate of hierarchical mergers are disfavored, consistent with previous population analyses. Future gravitational-wave events will further constrain the inputs to this generic hierarchical merger model, enabling a deeper look into the formation environments of BBHs.
Dusty Cloud Acceleration with Multiband Radiation
Authors: Huang 黄小 Xiaoshan 珊 , Davis Shane W. , Zhang Dong 
Published: April 2020

Abstract
We perform two-dimensional and three-dimensional simulations of cold, dense clouds, which are accelerated by radiation pressure on dust relative to a hot, diffuse background gas. We examine the relative effectiveness of acceleration by ultraviolet (UV) and infrared (IR) radiation fields, both independently and acting simultaneously on the same cloud. We study clouds that are optically thin to IR emission but with varying UV optical depths. Consistent with previous work, we find relatively efficient acceleration and long cloud survival times when the IR band flux dominates over the UV flux. However, when the UV flux is dominant or even a modest percentage (∼5%–10%) of the IR irradiating flux, it can act to compress the cloud, first crushing it and then disrupting the outer layers. This drives mixing of the outer regions of the dusty gas with the hot diffuse background to the point where most dust is not likely to survive or stay coupled to the gas. Hence, the cold cloud is unable to survive for a long enough timescale to experience significant acceleration before disruption even though efficient IR cooling keeps the majority of the gas close to the radiative equilibrium temperature (T ≲ 100 K). We discuss the implications for observed systems, concluding that radiation pressure driving is most effective when the light from star-forming regions is efficiently reprocessed into the IR.

Abstract
In our previous analysis we investigated the large-scale environment of two samples of radio galaxies (RGs) in the local universe (i.e., with redshifts z
src ≤ 0.15), classified as FR I and FR II on the basis of their radio morphology. The analysis was carried out using (i) extremely homogeneous catalogs and (ii) a new method, known as cosmological overdensity, to investigate their large-scale environments. We concluded that, independently of the shape of their radio extended structure, RGs inhabit galaxy-rich large-scale environments with similar characteristics and richness. In the present work, we first highlight additional advantages of our procedure, which does not suffer cosmological biases and/or artifacts, and then we carry out an additional statistical test to strengthen our previous results. We also investigate properties of RG environments using those of the cosmological neighbors. We find that large-scale environments of both FR Is and FR IIs are remarkably similar and independent of the properties of central RG. Finally, we highlight the importance of comparing radio sources in the same redshift bins to obtain a complete overview of their large-scale environments.

Abstract
CatWISE is a program to catalog sources selected from combined WISE and NEOWISE all-sky survey data at 3.4 and 4.6 μm (W1 and W2). The CatWISE Preliminary Catalog consists of 900,849,014 sources measured in data collected from 2010 to 2016. This data set represents four times as many exposures and spans over 10 times as large a time baseline as that used for the AllWISE Catalog. CatWISE adapts AllWISE software to measure the sources in coadded images created from six-month subsets of these data, each representing one coverage of the inertial sky, or epoch. The catalog includes the measured motion of sources in eight epochs over the 6.5 yr span of the data. From comparison to Spitzer, signal-to-noise ratio = 5 limits in magnitudes in the Vega system are W1 = 17.67 and W2 = 16.47, compared to W1 = 16.96 and W2 = 16.02 for AllWISE. From comparison to Gaia, CatWISE positions have typical accuracies of 50 mas for stars at W1 = 10 mag and 275 mas for stars at W1 = 15.5 mag. Proper motions have typical accuracies of 10 mas yr−1 and 30 mas yr−1 for stars with these brightnesses, an order of magnitude better than from AllWISE. The catalog is available in the WISE/NEOWISE Enhanced and Contributed Products area of the NASA/IPAC Infrared Science Archive.
Karl Löwith et la critique de l’existence historique
Authors: Fagniez Guillaume 
Published: April 2020

Cette étude examine la « critique de l’existence historique » de Karl Löwith, en éclairant son émergence, sa signification, et sa portée actuelle. On distingue ici l’enquête de Löwith sur les « présupposés théologiques de la philosophie de l’histoire » et sa critique radicale du « monde historique ». Tout en mettant en évidence les difficultés d’un dépassement du paradigme moderne de l’histoire, l’article s’interroge sur la place de l’œuvre de Löwith au sein d’une réévaluation d’ensemble des rapports entre nature et histoire.

Auteur d’une œuvre encore mal connue hors du Brésil, il est également un théoricien de l’architecture tout à fait original. Cet article vise à présenter synthétiquement les grands thèmes de cette pensée en architecture qui entretisse sans cesse esthétique et politique sous le mot d’ordre d’une architecture « opportune ».
Les familles transnationales et le deuil
Authors: Amadini Monica , Cadei Livia 
Published: April 2020

Les migrations ne concernent pas des lieux éloignés et marqués par des relations sociales indépendantes les unes des autres reliées par un mouvement entre deux communautés distinctes. Comment les familles gèrent-elles les liens dans le déplacement géographique ? Comment construisent-elles leur identité ? Si les études portant sur les familles transnationales ont déjà abordé ces questions, plus rares sont celles ayant porté sur l’expérience du deuil. Cet article se focalise sur la question de la migration des familles transnationales et propose, en particulier, une recherche exploratoire sur l’impact et l’élaboration du deuil dans les relations des familles immigrées. Il examine notamment les différentes influences présentes dans les expériences de deuil.
