Equilibrium Points and Networks of Periodic Orbits in the Pseudo-Newtonian Planar Circular Restricted Three-body Problem
Authors: Alrebdi H. I. , Papadakis Konstantinos E. , Dubeibe Fredy L. , Zotos Euaggelos E. 
Published: January 2022

Abstract
We explore a pseudo-Newtonian planar circular restricted three-body problem in which the primaries are modeled using an approximate gravitational potential up to the second nonvanishing term of the Fodor–Hoenselaers–Perjés expansion. We aim to understand how the main free parameters of the system affect its dynamical properties. In particular, we determine how the mass of the primaries as well as the transition parameters affect not only the properties of the points of equilibrium (total number, locations, and linear stability) but also the networks of simple symmetric periodic orbits. Our results show that, under this approach, significant variations are observed in the fixed points (number and stability) and periodic orbits of the planar circular restricted three-body problem, even when small contributions of the non-Newtonian terms are considered. We also provide direct applications of the new model potential in real observable binary stellar systems.
How are Lyα Absorbers in the Cosmic Web Related to Gas-rich Galaxies?
Authors: Borthakur Sanchayeeta 
Published: January 2022

Abstract
We present the correlation between Lyα absorbers and H i galaxies in the nearby universe (0.01 ≤ z ≤ 0.057). We find that Lyα absorbers are strongly correlated to H i galaxies at a projected separation of ≤0.5 Mpc and velocity separation of ≤50 km s−1. Lyα absorbers are 7.6 times more likely to be found near H i galaxies compared to a random distribution. The strength of correlations drops as the projected and/or velocity separation increases. We also find the correlation between Lyα absorbers and H i galaxies to be stronger than those observed between Lyα absorbers and optically selected galaxies. There is an enhancement in the number of absorbers at velocity separations of ≤30 km s−1 from galaxies at distances larger than their viral radius. Combined with the fact that most of our galaxies are not driving strong outflows, we conclude that the absorbers at low-velocity separations are tracing reservoirs of cooler gas around galaxies. This conclusion is consistent with the predictions from cosmological simulations where faint gas from the IGM flows into the disks of galaxies leading to galaxy growth.

Abstract
We present new discoveries and results from long-term timing of 72 pulsars discovered in the Pulsar Arecibo L-band Feed Array (PALFA) survey, including precise determination of astrometric and spin parameters, and flux density and scatter broadening measurements at 1.4 GHz. Notable discoveries include two young pulsars (characteristic ages ∼30 kyr) with no apparent supernova remnant associations, three mode-changing, 12 nulling and two intermittent pulsars. We detected eight glitches in five pulsars. Among them is PSR J1939+2609, an apparently old pulsar (characteristic age ∼1 Gy), and PSR J1954+2529, which likely belongs to a newly emerging class of binary pulsars. The latter is the only pulsar among the 72 that is clearly not isolated: a nonrecycled neutron star with a 931 ms spin period in an eccentric (e = 0.114) wide (P

b
= 82.7 days) orbit with a companion of undetermined nature having a minimum mass of ∼0.6 M
⊙. Since operations at Arecibo ceased in 2020 August, we give a final tally of PALFA sky coverage, and compare its 207 pulsar discoveries to the known population. On average, they are 50% more distant than other Galactic plane radio pulsars; PALFA millisecond pulsars (MSPs) have twice the dispersion measure per unit spin period than the known population of MSP in the plane. The four intermittent pulsars discovered by PALFA more than double the population of such objects, which should help to improve our understanding of pulsar magnetosphere physics. The statistics for these, rotating radio transients, and nulling pulsars suggest that there are many more of these objects in the Galaxy than was previously thought.
Galactic Mass Estimates Using Dwarf Galaxies as Kinematic Tracers
Authors: Slizewski Anika , Dufresne Xander , Murdock Keslen , Eadie Gwendolyn , Sanderson Robyn , Wetzel Andrew , Jurić Mario 
Published: January 2022

Abstract
New mass estimates and cumulative mass profiles with Bayesian credible regions for the Milky Way (MW) are found using the Galactic Mass Estimator (GME) code and dwarf galaxy (DG) kinematic data from multiple sources. GME takes a hierarchical Bayesian approach to simultaneously estimate the true positions and velocities of the DGs, their velocity anisotropy, and the model parameters for the Galaxy’s total gravitational potential. In this study, we incorporate meaningful prior information from past studies and simulations. The prior distributions for the physical model are informed by the results of Eadie & Jurić, who used globular clusters instead of DGs, as well as by the subhalo distributions of the Ananke Gaia-like surveys from Feedback in Realistic Environments-2 cosmological simulations (see Sanderson et al.). Using DGs beyond 45 kpc, we report median and 95% credible region estimates for r
200 = 212.8 (191.12, 238.44) kpc, and for the total enclosed mass M
200 = 1.19 (0.87, 1.68) × 1012
M
⊙ (adopting Δ
c
= 200). Median mass estimates at specific radii are also reported (e.g., M (< 50 kpc) = 0.52 × 1012
M
⊙ and M (100 kpc) = 0.78 × 1012
M
⊙). Estimates are comparable to other recent studies using Gaia DR2 and DGs, but notably different from the estimates of Eadie & Jurić. We perform a sensitivity analysis to investigate whether individual DGs and/or a more massive Large Magellanic Cloud on the order of 1011
M
⊙ may be affecting our mass estimates. We find possible supporting evidence for the idea that some DGs are affected by a massive LMC and are not in equilibrium with the MW.
Probing the Spins of Supermassive Black Holes with Gravitational Waves from Surrounding Compact Binaries
Authors: Liu Bin , Lai Dong 
Published: January 2022

Abstract
Merging compact black hole (BH) binaries are likely to exist in the nuclear star clusters around supermassive BHs (SMBHs), such as Sgr A*. They may also form in the accretion disks of active galactic nuclei. Such compact binaries can emit gravitational waves (GWs) in the low-frequency band (0.001–1 Hz) that are detectable by several planned space-borne GW observatories. We show that the angular momentum vector of the compact binary (
L

in) may experience significant variation due to the frame-dragging effect associated with the spin of the SMBH. The dynamical behavior of
L

in can be understood analytically as a resonance phenomenon. We show that the rate of change of
L

in encodes the information on the spin of the SMBH. Therefore, detecting GWs from compact binaries around SMBHs, particularly the modulation of the waveform associated with the variation of
L

in, can provide a new probe of the spins of SMBHs.
The Accretion Flow in M87 is Really MAD
Authors: Yuan Feng , Wang Haiyang , Yang Hai 
Published: January 2022

Abstract
The supermassive black holes in most galaxies in the universe are powered by hot accretion flows. Both theoretical analysis and numerical simulations have indicated that, depending on the degree of magnetization, black hole hot accretion flow is divided into two modes, namely SANE (standard and normal evolution) and MAD (magnetically arrested disk). It has been an important question which mode the hot accretion flows in individual sources should belong to in reality, SANE or MAD. This issue has been investigated in some previous works but they all suffer from various uncertainties. By using the measured rotation measure (RM) values in the prototype low-luminosity active galactic nuclei in M87 at 2, 5, and 8 GHz along the jet at various distances from the black hole, combined with three-dimensional general relativity magnetohydrodynamical numerical simulations of SANE and MAD, we show in this paper that the RM values predicted by MAD are well consistent with observations, while the SANE model overestimates the RM by over two orders of magnitude and thus is ruled out.
Ground beetles (Carabidae) in urban habitats of Kaluga City (Russia)
Authors: Aleksanov Victor , Alekseev Sergey , Shashkov Maxim 
Published: January 2022

Ground beetles (Carabidae, Coleoptera) are one of the most species-rich and well-studied insect families. However, the number of published datasets is disproportionately low against the biodiversity of this group. According to GBIF, only a fifth of the percentage of all published data covers ground beetles. This article describes a sampling-event dataset providing primary data on ground beetles collected in urban and suburban habitats in Kaluga, a typical central Russian city. We surveyed habitats of different land-use types and the extent and intensity of anthropogenic influence: yards, gardens, quarries, small urban woodlands, grasslands and riparian habitats. Carabids were collected by pitfall traps during most of the vegetative season (mostly from late April - early May to at least early October) for 13 seasons between 1994 and 2015. In total, the dataset contains 189 carabid species and 79,091 specimens. The dataset provides information about species composition and abundance, habitat distribution, seasonal and long-term dynamics of carabid beetles in environments of different degrees of urbanisation.
This dataset is the first sampling-event dataset about carabids in various urban habitats published through GBIF.
COVID-19 en Côte d’Ivoire : la « figure sociale » de la maladie à Abidjan
Authors: Lida Dali Serge , Ballet Jérôme 
Published: January 2022

La COVID-19 a touché l’Afrique comme le reste du monde. On peut néanmoins penser que la représentation que se font les populations de cette pandémie diffère fortement d’un pays à l’autre. À partir d’une enquête qualitative, nous en analysons la représentation sociale en Côte d’Ivoire et plus spécialement à Abidjan, principal foyer de contamination. Nos résultats mettent en évidence que la « figure sociale » de cette maladie y est marquée, d’une part, par la vision ancrée dans le clientélisme des interdictions et autorisations liées aux restrictions imposées, et, d’autre part, par une forme de banalisation qui résulte de ses caractéristiques propres de « massification », de « généralisation » et de « naturalisation », au regard, notamment, de celles du VIH-SIDA ou de la fièvre Ebola.

L’agroécologie face aux croyances. Le cas de Mankosi en Afrique du Sud
Authors: Besse Karine , Del Corso Jean-Pierre 
Published: January 2022

L’agroécologie gagne en popularité dans les pays du sud, pourtant l’usage d’intrants chimiques y reste très répandu. Prenant la forme de croyances, des obstacles mentaux s’opposent à une révision de cette pratique. Mobilisant la théorie de l’objectivisme positionnel d’Amartya Sen et s’appuyant sur le cas des cultivateurs/trices de Mankosi en Afrique du Sud, cette étude évalue plus particulièrement l’influence de différents paramètres socioculturels sur l’emploi d’insecticides. Elle suggère que l’adoption de pratiques reposant davantage sur la valorisation des processus naturels ne pourra se réaliser sans un déplacement des positions d’observation des cultivateurs/trices vis-à-vis de cet emploi.
