ALMA observations reveal no preferred outflow--filament and outflow--magnetic field orientations
T. Baug, Ke Wang, Tie Liu +12
We present a statistical study on the orientation of outflows with respect to large-scale filaments and the magnetic fields. Although filaments are widely observed toward Galactic…
Metallicity and -element Abundance Gradients along the Sagittarius Stream as Seen by APOGEE
Christian R. Hayes, Steven R. Majewski, Sten Hasselquist +27
Using 3D positions and kinematics of stars relative to the Sagittarius (Sgr) orbital plane and angular momentum, we identify 166 Sgr stream members observed by the Apache Point Obs…
Formation and Evolution of Compact Object Binaries in AGN Disks
Hiromichi Tagawa, Zoltan Haiman, Bence Kocsis
The astrophysical origin of gravitational wave (GW) events discovered by LIGO/VIRGO remains an outstanding puzzle. In active galactic nuclei (AGN), compact-object binaries form, ev…
Binary intermediate-mass black hole mergers in globular clusters
Alexander Rasskazov, Giacomo Fragione, Bence Kocsis
We consider the formation of binary intermediate black holes (BIMBH) in globular clusters (GC), which could happen either in situ or due to the mergers between clusters. We simulat…
The Sixteenth Data Release of the Sloan Digital Sky Surveys: First Release from the APOGEE-2 Southern Survey and Full Release of eBOSS Spectra
Romina Ahumada, Carlos Allende Prieto, Andres Almeida +310
This paper documents the sixteenth data release (DR16) from the Sloan Digital Sky Surveys; the fourth and penultimate from the fourth phase (SDSS-IV). This is the first release of…
X-ray Signatures of Black Hole Feedback: Hot Galactic Atmospheres in IllustrisTNG and X-ray Observations
Nhut Truong, Annalisa Pillepich, Norbert Werner +6
Hot gaseous atmospheres that permeate galaxies and extend far beyond their stellar distribution, where they are commonly referred to as the circumgalactic medium (CGM), imprint imp…
PS1-STRM: Neural network source classification and photometric redshift catalogue for PS1 DR1
Róbert Beck, István Szapudi, Heather Flewelling +2
The Pan-STARRS1 (PS1) survey is a comprehensive optical imaging survey of three quarters of the sky in the broad-band photometric filters. We present the methodology u…
Unveiling the weak radio quasar population at z 4
Krisztina Perger, Sándor Frey, Krisztina É. Gabányi +1
We applied image stacking on empty-field Faint Images of the Radio Sky at Twenty-Centimeters (FIRST) survey maps centred on optically identified high-redshift quasars at t…
Effective spin distribution of black hole mergers in triples
Giacomo Fragione, Bence Kocsis
Many astrophysical scenarios have been proposed to explain the several black hole (BH) and neutron star binary mergers observed via gravitational waves (GWs) by the LIGO-Virgo coll…
Multi-scale analysis of the Monoceros OB 1 star-forming region: II. Colliding filaments in the Monoceros OB1 molecular cloud
Julien Montillaud, Mika Juvela, Charlotte Vastel +24
We started a multi-scale analysis of G202.3+2.5, an intertwined filamentary region of Monoceros OB1. In Paper I, we examined the distributions of dense cores and protostars and fou…
Multi-scale analysis of the Monoceros OB 1 star-forming region: I. The dense core population
Julien Montillaud, Mika Juvela, Charlotte Vastel +24
Current theories and models attempt to explain star formation globally, from core scales to giant molecular cloud scales. A multi-scale observational characterisation of an entire…
Very long baseline interferometry observation of the triple AGN candidate J0849+1114
Krisztina Éva Gabányi, Sándor Frey, Shobita Satyapal +2
In the hierarchical structure formation model, galaxies grow through various merging events. Numerical simulations indicate that the mergers can enhance the activity of the central…
Exploring the pattern of the Galactic HI foreground of GRBs with the ATCA
H. Denes, P. A. Jones, L. V. Toth +12
The afterglow of a gamma ray burst (GRB) can give us valuable insight into the properties of its host galaxy. To correctly interpret the spectra of the afterglow we need to have a…
Making a supermassive star by stellar bombardment
Hiromichi Tagawa, Zoltan Haiman, Bence Kocsis
Approximately two hundred supermassive black holes (SMBHs) have been discovered within the first Gyr after the Big Bang. One pathway for the formation of SMBHs is through the…
Intermediate mass black holes' effect on compact object binaries
Barnabás Deme, Yohai Meiron, Bence Kocsis
Although their existence is not yet confirmed observationally, intermediate mass black holes (IMBHs) may play a key role in the dynamics of galactic nuclei. In this paper, we negle…
Iron abundance distribution in the hot gas of merging galaxy clusters
I. Urdampilleta, F. Mernier, J. S. Kaastra +4
We present XMM-Newton/EPIC observations of six merging galaxy clusters and study the distributions of their temperature, iron (Fe) abundance and pseudo-entropy along the merging ax…
Constraining the dark matter halo mass of isolated low-surface-brightness galaxies
Orsolya E. Kovacs, Akos Bogdan, Rebecca E. A. Canning
Recent advancements in the imaging of low-surface-brightness objects revealed numerous ultra-diffuse galaxies in the local Universe. These peculiar objects are unusually extended a…
Extended X-ray study of M49: the frontier of the Virgo Cluster
Y. Su, R. P. Kraft, P. E. J. Nulsen +10
The M49 group, resident outside the virial radius of the Virgo cluster, is falling onto the cluster from the south. We report results from deep {\sl XMM-Newton} mosaic observations…
Tidal disruption events onto stellar black holes in triples
Giacomo Fragione, Nathan Leigh, Rosalba Perna +1
Stars passing too close to a black hole can produce tidal disruption events (TDEs), when the tidal force across the star exceeds the gravitational force that binds it. TDEs have us…
