Herschel and SCUBA-2 observations of dust emission in a sample of Planck cold clumps
Mika Juvela, Jinhua He, Katherine Pattle +26
Analysis of all-sky Planck submillimetre observations and the IRAS 100um data has led to the detection of a population of Galactic cold clumps. The clumps can be used to study star…

The TOP-SCOPE survey of Planck Galactic Cold Clumps: Survey overview and results of an exemplar source, PGCC G26.53+0.17
Tie Liu, Kee-Tae Kim, Mika Juvela +11
The low dust temperatures (<14 K) of Planck Galactic Cold Clumps (PGCCs) make them ideal targets to probe the initial conditions and very early phase of star formation. TOP-SCOPE i…
VALES: IV. Exploring the transition of star formation efficiencies between normal and starburst galaxies using APEX/SEPIA Band-5 and ALMA at low redshift

In this work we present new APEX/SEPIA Band-5 observations targeting the CO () emission line of 24 Herschel-detected galaxies at . Combining this sample {w…
Diffuse X-ray-emitting Gas in Major Mergers
Beverly J. Smith, Kristen Campbell, Curtis Struck +5
Using archived data from the Chandra X-ray telescope, we have extracted the diffuse X-ray emission from 49 equal-mass interacting/merging galaxy pairs in a merger sequence, from wi…
Rediscovering the Galactic outer disk with LAMOST data
Chao Liu, Yan Xu, Haifeng Wang +1
From the derived stellar density profile using LAMOST giant stars, we find that the Galactic disk does not show truncation or break, but smoothly transit to the halo from 19 kpc. T…
The age-velocity dispersion relation of the Galactic discs from LAMOST-Gaia data
Jincheng Yu, Chao Liu
We present the age-velocity dispersion relation (AVR) in three dimensions in the solar neighbourhood using 3,564 commonly observed sub-giant/red-giant branch stars selected from LA…
Probing satellite galaxies in the Local Group by using FAST
Jing Li, Yougang Wang, Minzhi Kong +3
The abundance of neutral hydrogen (HI) in satellite galaxies in the Local Group is important for studying the formation history of our Local Group. In this work, we generated mock…
Pulsar Rotation Measures and Large-scale Magnetic Field Reversals in the Galactic Disk
J. L. Han, R. N. Manchester, W. van Straten +1
We present the measurements of Faraday rotation for 477 pulsars observed by the Parkes 64-m radio telescope and the Green Bank 100-m radio telescope. Using these results along with…
SDSS-IV MaNGA: A Distinct Mass Distribution Explored in Slow-Rotating Early-type Galaxies
Yu Rong, Hongyu Li, Jie Wang +8
We study the radial acceleration relation (RAR) for early-type galaxies (ETGs) in the SDSS MaNGA MPL5 dataset. The complete ETG sample show a slightly offset RAR from the relation…
Supermassive black holes coalescence mediated by massive perturbers: implications for gravitational waves emission and nuclear cluster formation
Manuel Arca Sedda, Peter Berczik, Roberto Capuzzo-Dolcetta +3
A large fraction of galactic nuclei is expected to host supermassive black hole binaries (BHB), likely formed during the early phase of galaxies assembly and merging. In this paper…
Massive outflows associated with ATLASGAL clumps
Aiyuan Yang, Mark Thompson, James Urquhart +1
We have undertaken the largest survey for outflows within the Galactic Plane using simultaneously observed 13CO and C18O data. 325 out of a total of 919 ATLASGAL clumps have data s…
The ALMA Frontier Fields Survey - IV. Lensing-corrected 1.1 mm number counts in Abell 2744, MACSJ0416.1-2403 and MACSJ1149.5+2223
A. M. Muñoz Arancibia, J. González-López, E. Ibar +15
[abridged] Characterizing the number counts of faint, dusty star-forming galaxies is currently a challenge even for deep, high-resolution observations in the FIR-to-mm regime. They…
Heavy X-ray obscuration in the most-luminous galaxies discovered by WISE
F. Vito, W. N. Brandt, D. Stern +11
Hot Dust-Obscured Galaxies (Hot DOGs) are hyperluminous () infrared galaxies with extremely high (up to hundreds of K) dust tempe…
Filamentary Flows and Clump-fed High-mass Star Formation in G22
Jinghua Yuan, Jin-Zeng Li, Yuefang Wu
G22 is a hub-filament system composed of four supercritical filaments. Velocity gradients are detected along three filaments. A total mass infall rate of 440 ~Myr w…
Host galaxy properties of mergers of stellar binary black holes and their implications for advanced LIGO gravitational wave sources
Liang Cao, Youjun Lu, Yuetong Zhao
Understanding the host galaxy properties of stellar binary black hole (SBBH) mergers is important for revealing the origin of the SBBH gravitational-wave sources detected by advanc…
