The ALFALFA-SDSS Galaxy Catalog
Authors: Durbala Adriana , Finn Rose A. , Odekon Mary Crone , Haynes Martha P. , Koopmann Rebecca A. , O’Donoghue Aileen A. 
Published: November 2020

Abstract
We present a H i optical catalog of ∼30,000 galaxies based on the 100% complete Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) survey combined with data from the Sloan Digital Sky Survey (SDSS). Our goal is to facilitate the public use of the completed ALFALFA catalog by providing carefully determined matches to SDSS counterparts, including matches for ∼10,000 galaxies that do not have SDSS spectra. These identifications can provide a basis for further crossmatching with other surveys using SDSS photometric IDs as a reference point. We derive absolute magnitudes and stellar masses for each galaxy using optical colors combined with an internal reddening correction designed for small- and intermediate-mass galaxies with active star formation. We also provide measures of stellar masses and star formation rates based on infrared and/or ultraviolet photometry for galaxies that are detected by the Wide-field Infrared Survey Explorer and/or the Galaxy Evolution Explorer. Finally, we compare the galaxy population in the ALFALFA-SDSS sample with the populations in several other publicly available galaxy catalogs and confirm that ALFALFA galaxies typically have lower masses and bluer colors.

Published: November 2020

Abstract
Statistics of low-mass pre-main-sequence binaries in the Orion OB1 association with separations ranging from 0.″6 to 20″ (220 to 7400 au at 370 pc) are studied using images from the VISTA Orion mini survey and astrometry from Gaia. The input sample based on the CVSO catalog contains 1137 stars of K and M spectral types (masses between 0.3 and 0.9

), 1021 of which are considered to be association members. There are 135 physical binary companions to these stars with mass ratios above ∼0.13. The average companion fraction is 0.09 ± 0.01 over 1.2 decades in separation, slightly less than, but still consistent with, the field. We found a difference between the Ori OB1a and OB1b groups, the latter being richer in binaries by a factor of 1.6 ± 0.3. No overall dependence of the wide-binary frequency on the observed underlying stellar density is found, although in the Ori OB1a off-cloud population, these binaries seem to avoid dense clusters. The multiplicity rates in Ori OB1 and in sparse regions like Taurus differ significantly, hinting that binaries in the field may originate from a mixture of diverse populations.
Examining the Relationship Between Convective Core Overshoot and Stellar Properties Using Asteroseismology
Authors: Viani Lucas S. , Basu Sarbani 
Published: November 2020

Abstract
Core overshoot is a large source of uncertainty in constructing stellar models. Whether the amount of overshoot is constant or mass dependent is not completely known, even though models sometimes assume a mass-based trend. In this work we use asteroseismic data from stars observed by Kepler to investigate the relationship between various stellar properties and the amount of overshoot needed to properly model a given star. We find a strong positive trend between stellar mass and overshoot amount for stars between 1.1 and 1.5

, with a slope of 0.89. Additionally, we investigate how inferred stellar properties change as a function of overshoot. Our model grids show that the inferred stellar mass and radius can vary by as much as 14% and 6%, respectively, depending on the extent of overshoot. This mass spread results in a commensurate spread in the ages.
Clumpy Wind Accretion in Cygnus X-1
Authors: Palit Ishika , Janiuk Agnieszka , Czerny Bozena 
Published: November 2020

Abstract
Cygnus X-1 is one of the brightest X-ray sources observed and shows the X-ray intensity variations on timescales from milliseconds to months in both the soft and hard X-rays. The accretion onto the black hole is believed to be wind fed due to focused stellar wind from the binary companion HDE-226868. We aim to understand the physical mechanism responsible for the short timescale X-ray variability (<100 s) of the source in its hard/low state. We compute the 2D relativistic hydrodynamic simulation of the low angular momentum accretion flow with a time-dependent outer boundary condition that reflects the focused, clumpy wind from the supergiant in this X-ray binary system. We follow the dynamical evolution of our model for about 100 s and present the results showing an oscillatory shock, being a potential explanation of variability observed in hard X-rays. The simulated model with shock solutions is in good agreement with the observed power density spectra of the source.
Characterizing [C ii] Line Emission in Massive Star-forming Clumps

Published: November 2020

Abstract
Because the 157.74 μm [C ii] line is the dominant coolant of star-forming regions, it is often used to infer the global star formation rates of galaxies. By characterizing the [C ii] and far-infrared emission from nearby Galactic star-forming molecular clumps, it is possible to determine whether extragalactic [C ii] emission arises from a large ensemble of such clumps, and whether [C ii] is indeed a robust indicator of global star formation. We describe [C ii] and far-infrared observations using the FIFI-LS instrument on the Stratospheric Observatory For Infrared Astronomy (SOFIA) airborne observatory toward four dense, high-mass, Milky Way clumps. Despite similar far-infrared luminosities, the [C ii] to far-infrared luminosity ratio,

/L
FIR, varies by a factor of at least 140 among these four clumps. In particular, for AGAL313.576+0.324, no [C ii] line emission is detected despite a FIR luminosity of 24,000

. AGAL313.576+0.324 lies a factor of more than 100 below the empirical correlation curve between

/L
FIR and

found for galaxies. AGAL313.576+0.324 may be in an early evolutionary “protostellar” phase with insufficient ultraviolet flux to ionize carbon, or in a deeply embedded “‘hypercompact”

region phase where dust attenuation of UV flux limits the region of ionized carbon to undetectably small volumes. Alternatively, its apparent lack of [C ii] emission may arise from deep absorption of the [C ii] line against the 158 μm continuum, or self-absorption of brighter line emission by foreground material, which might cancel or diminish any emission within the FIFI-LS instrument’s broad spectral resolution element (

km s−1).
Massive Black Hole Merger Rates: The Effect of Kiloparsec Separation Wandering and Supernova Feedback
Authors: Barausse Enrico , Dvorkin Irina , Tremmel Michael , Volonteri Marta , Bonetti Matteo 
Published: November 2020

Abstract
We revisit the predictions for the merger rate of massive black hole binaries detectable by the Laser Interferometer Space Antenna (LISA) and their background signal for pulsar-timing arrays. We focus on the effect of the delays between the merger of galaxies and the final coalescence of black hole binaries, and on supernova feedback on the black hole growth. By utilizing a semianalytic galaxy formation model, not only do we account for the driving of the evolution of binaries at separations ≲1 pc (gas-driven migration, stellar hardening, and triple/quadruple massive black hole systems), but we also improve on previous studies by accounting for the time spent by black hole pairs from kiloparsec down to parsec separation. We also include the effect of supernova feedback, which may eject gas from the nuclear region of low-mass galaxies, thus hampering the growth of black holes via accretion and suppressing their orbital migration in circumbinary disks. Despite including these novel physical effects, we predict that the LISA detection rate should still be

, irrespective of the model for the black hole seeds at high redshifts. Scenarios where black holes form from

seeds are more significantly impacted by supernova feedback. We also find that for detectable events, the merging black holes typically have mass ratios between ∼0.1 and 1. Predictions for the stochastic background in the band of pulsar-timing array experiments are instead rather robust and show only a mild dependence on the model.

Published: November 2020

Background Disruptions due to the COVID-19 pandemic have forced medical schools around the world to adapt. Major changes in curriculum delivery during the pandemic have impacted medical students’ professional development. We assess undergraduate medical students’ adaptations and Professional Identity Formation (PIF) by exploring their written reflections. Methods This phenomenology study analyzes undergraduate medical students’ written reflections. We perform a thematic analysis to identify emerging themes. Results We purposively selected 80 written reflections, considering the students’ year of study, gender, GPA, and education stage (preclinical or clinical). Three themes emerged: students’ adaptation processes and coping strategies in facing the pandemic; their adaptation processes for learning; and their perceived roles as medical students during the pandemic. Conclusions Adaptive coping mechanisms were implemented by the medical students in this study. The socialization processes that promote professional identity formation may change due to the tremendous disruption wrought by the pandemic; this has prompted our investigation of students’ roles and various ways of interacting with role models. We highlight the importance of the medical school supporting students’ adaptations and professional identity formation during this pandemic.

This paper discusses the educational values contained in Q.S. al-Isra' ([17]: 23-25) and its actualization in the modern world. This article shows that, first, the educational values contained in Q.S. al-Isra '(17: 23-25), namely (1) the Aqidah education which Allah obliges His servants to press Him in worship and in worship and forbid them to associate Allah with anything or anyone. Therefore, the one who deserves the highest honors is the one who created nature and everything in it that is Allah Almighty. (2) Education of birrul walidain, after Allah commanded that not worship other than Him then Allah commanded to the Muslims so that they really pay attention to the devotional services to both mothers father and do not regard it as a trivial affair, by explaining that God is the more know what thrilled in their hearts. Second, the actualization of educational values based on Q.S. al-Isra '(17: 23-25) in the modern world, namely (1) education of the creeds in schools should teach the students in union of God that there is no god worthy to be worshiped besides Allah the Almighty God. The limited number of hours of lesson with the tarnished material causes the religious teacher to take the easiest shortcut, that is, to see religious education is no more a lesson than an education. (2) Education of birrul walidain in the modern world today is the treatment of elderly parents is really upside down. When they need more attention from the closest people, especially a child, instead they are mostly alienated from the family on the grounds to get better attention. Finally, they are deposited in nursing homes or others.
Zakat Mal dalam Perspektif Hadis Maudhu'iy
Authors: Hamzah Hamzah 
Published: November 2020

One of the major problems that the developing countries face is the lack of state revenues to cover all required expenses. Zakat is completely different from taxes, because it is a direct solution for poor people because it goes with the same type of property from the rich to the poor (not like the most of the poverty reduction programms which go in shape of projects for the poor), also Zakat has its own fixed resources and fixed legal channels of spending. Zakat is considered a form of charity that must be paid from a person`s wealth (when his/her wealth exceeds or reaches a “specific amount” of money (or othertypes of wealth like gold) So when the wealth reaches this level or (the specific amount ) the person who owns this wealth should pay a specific amount for the poor and this amount goes to the poor named Zakat. At the time of prophet Mohamed, he was sending the officials to collect money of Zakat, as it was mentioned for example , when he sent Muaaz Ibnu Jabal to govern Yemen, he ordered him to collect money of Zakat. Also in the time of the second gonernant in Islam (Khalifah). At the time of the third Khalifah Umar, where the state was expanded, Umar still interes ed in collecting Zakat but with a new way in terms of two perspectives, first collecting it from both outward and inward money, second by establishing “a Zakat organization” to be the ideal solution in dealing with Zakat. At the time of umar the revenues of Zakat became a huge amount, until Umar decided to give a salary for The periods after that the governants were not interested so much to collect Zakat by themselves and from the outward and inward money, because total toll became very huge so they decided to leave this mater up to the eligible Muslims to pay their Zakat, but in the later on periods of time the Muslims became less aware by the religious practises so the total toll of Zakat became less than periods of the prophet and Khalifah and not sufficient to satisfy the basic needs of the poor in the Muslim countries. To conclude from that, the best total yield of Zakat was happened when it was collected and distributed through an organization with a great attention from the leader of the state, so this paper will be describe about zakat persepective Hadis Maudu’ in the first time of Islam.
