Black hole disks in galactic nuclei by Szölgyén, A, Kocsis, B

“…This explains the origin of the clockwise disk in the Galactic center and predicts a population of black holes (BHs) embedded within this structure. …”

Resonant dynamical friction in nuclear star clusters: rapid alignment of an intermediate-mass black hole with a stellar disk by Szolgyen, A, Mathe, G, Kocsis, B

“…This process may offer a test for the viability of IMBH candidates in the Galactic Center. Resonant dynamical friction is not limited to IMBHs; any object much more massive than disk particles may ultimately align with the disk. …”

Multiscale Modeling of Astrophysical Jets by James H. Beall, John Guillory, David V. Rose, Michael T. Wolff

“…A preliminary simulation of a jet from the galactic center region is used to lend credence to the jet as the source of the so-called the Fermi Bubble (see, e.g., Su, M. …”

Mapping the high ionization rate of the GC starburst Sgr B2 through low HCO+ /N2H+ J=1-0 intensity ratios by Santa-Maria Miriam G., Goicoechea Javier R.

“…The starburst Sgr B2, in the Galactic Center (GC), is an excellent template to spatially resolve the high-mass star-forming cores from the extended cloud environment, and to study the properties of the warm neutral gas in conditions likely prevalent in star-forming galaxies. …”

Soft scattering evaporation of dark matter subhalos by inner galactic gases by Xiao-jun Bi, Yu Gao, Mingjie Jin, Yugen Lin, Qian-Fei Xiang

“…We calculate the subhalos evaporation rate and show that subhalos lighter than $$10^{-5}M_{\odot }$$ 10 - 5 M ⊙ in the gaseous inner galactic region are subject to evaporation via dark matter’s effective electric and magnetic dipole moments below current direct detection limits, which potentially affects the low-mass subhalos distribution in the galactic center.…”

Enhanced n-body annihilation of dark matter and its indirect signatures by Mohammad Hossein Namjoo, Tracy R. Slatyer, Chih-Liang Wu

“…We examine the complementary constraints from the Galactic Center, Galactic halo, and galaxy clusters, and outline the circumstances under which each search would give rise to the strongest constraints. …”

Imprints of dark matter on black hole shadows using spherical accretions by K. Saurabh, Kimet Jusufi

“…Abstract We study the possibility of identifying dark matter in the galactic center from the physical properties of the electromagnetic radiation emitted from an optically-thin disk region around a static and spherically symmetric black hole. …”

Toward the IR Detection of Carbonic Acid: Absorption and Emission Spectra by Ryan C. Fortenberry, Vincent J. Esposito

“…With the recent radioastronomical detection of cis-trans- carbonic acid (H _2 CO _3 ) in a molecular cloud toward the Galactic center, the more stable but currently unobserved cis-cis conformer is shown here to have strong IR features. …”

Rotation Curve of the Milky Way and the Dark Matter Density by Yoshiaki Sofue

“…We review the current status of the study of rotation curve (RC) of the Milky Way, and present a unified RC from the Galactic Center to the galacto-centric distance of about 100 kpc. …”

Faraday Depolarization Effects in Spiral Galaxies by Mami Machida, Takuya Akahori, Kenji E. Nakamura, Hiroyuki Nakanishi, Marijke Haverkorn

“…We are interested in galactic magnetic fields because they affect the structural formation of galaxies in terms of star-forming regions, spiral arms, and threads at the galactic center. To clarify the importance of magnetic fields, we carried out numerical simulations of the galactic gaseous disk with magnetic fields. …”

Neutrinos below 100 TeV from the southern sky employing refined veto techniques to IceCube data by Arguelles Delgado, Carlos A, Axani, Spencer Nicholas, Collin, G. H., Conrad, Janet Marie, Moulai, Marjon H.

“…For the IceCube Neutrino Observatory located at the South Pole, the southern sky, containing the inner part of the Galactic plane and the Galactic Center, is a particularly challenging region at these energies, because of the large background of atmospheric muons. …”

Search for continuous gravitational wave emission from the Milky Way center in O3 LIGO-Virgo data by Sudhir, Vivishek

“…We present a directed search for continuous gravitational wave (CW) signals emitted by spinning neutron stars located in the inner parsecs of the Galactic Center (GC). Compelling evidence for the presence of a numerous population of neutron stars has been reported in the literature, turning this region into a very interesting place to look for CWs. …”

New look on the origin of cosmic rays by Istomin Ya.N.

“…Assuming the same nature of Galactic and extragalactic rays, we conclude that the Galactic rays were produced by a relativistic jet emitted from the Galactic center during the period of its activity in the past. …”

Mass Distribution in Rotating Thin-Disk Galaxies According to Newtonian Dynamics by James Q. Feng, C. F. Gallo

“…When a central spherical bulge is present, the mass distribution in the galaxy is altered in such a way that the periphery mass density is reduced, while more mass appears toward the galactic center. By extending the computational domain beyond the galactic edge, we can determine the rotation velocity outside the cut-off radius, which appears to continuously decrease and to gradually approach the Keplerian rotation velocity out over twice the cut-off radius. …”

A Statistical Estimation of the Occurrence of Extraterrestrial Intelligence in the Milky Way Galaxy by Xiang Cai, Jonathan H. Jiang, Kristen A. Fahy, Yuk L. Yung

Dark matter effect on the weak deflection angle by black holes at the center of Milky Way and M87 galaxies by Reggie C. Pantig, Ali Övgün

“…Abstract In this paper, we investigated the effect of dark matter on the weak deflection angle by black holes at the galactic center. We consider three known dark matter density profiles such as the Cold Dark Matter, Scalar Field Dark Matter, and the Universal Rotation Curve from the Burkert profile. …”
