CO-CHANGES I: IRAM 30m CO Observations of Molecular Gas in the Sombrero Galaxy
Yan Jiang, Jiang-Tao Li, Yu Gao +7
Molecular gas plays a critical role in explaining the quiescence of star formation (SF) in massive isolated spiral galaxies, which could be a result of either the low molecular gas…
In Search of Infall Motion in Molecular Clumps. IV. Mapping of the Global Infall Sources
Yang Yang, Xi Chen, Zhibo Jiang +3
We have used the IRAM 30-m telescope to map some targets with HCO (1-0) and HCO (1-0) lines in order to search for gas infall evidence in the clumps. In this paper,…
Searching for Radio Outflows from M31* with VLBI Observations
Sijia Peng, Zhiyuan Li, Lorant O. Sjouwerman +3
As one of the nearest and most dormant supermassive black holes (SMBHs), M31* provides a rare but promising opportunity for studying the physics of black hole accretion and feedbac…
A Chemical Study of Nine Star-forming Regions with Evidence of Infall Motion
Yang Yang, Yao Wang, Zhibo Jiang +1
The study of the physical and chemical properties of gas infall motion in the molecular clumps helps us understand the initial stages of star formation. We used the FTS wide-sideba…
The Role of Magnetic Fields in the Formation of the Filamentary Infrared Dark Cloud G11.11-0.12
Zhiwei Chen, Ramotholo Sefako, Yang Yang +4
We report on the near-infrared polarimetric observations of G11.11-0.12 (hereafter G11) obtained with SIRPOL on the 1.4 m IRSF telescope. The starlight polarisation of the backgrou…
CHANG-ES XXIX: The Sub-kpc Nuclear Bubble of NGC 4438
Jiang-Tao Li, Q. Daniel Wang, Theresa Wiegert +8
AGN bubbles could play an important role in accelerating high-energy CRs and galactic feedback. Only in nearby galaxies could we have high enough angular resolution in multi-wavele…
The Role of Magnetic Fields in Triggered Star Formation of RCW 120
Zhiwei Chen, Ramotholo Sefako, Yang Yang +3
We report on the near-infrared polarimetric observations of RCW 120 with the 1.4 m IRSF telescope. The starlight polarization of the background stars reveals for the first time the…
CHANG-ES. XXIV. First Detection of A Radio Nuclear Ring and Potential LLAGN in NGC 5792
Yang Yang, Judith Irwin, Jiangtao Li +8
We report the discoveries of a nuclear ring of diameter 10$\arcsec$ (1.5 kpc) and a potential low luminosity active galactic nucleus (LLAGN) in the radio continuum emission m…
Lightcurve Evolution of the nearest Tidal Disruption Event: A late-time, radio-only flare
Eric S. Perlman, Eileen T. Meyer, Q. Daniel Wang +6
Tidal disruption events (TDEs) occur when a star passes close enough to a galaxy's supermassive black hole to be disrupted by tidal forces. We discuss new observations of IGRJ12580…
In search of infall motion in molecular clumps III: HCO+ (1-0) and H13CO+ (1-0) mapping observations toward the confirmed infall sources
Yang Yang, Zhibo Jiang, Zhiwei Chen +2
The study of infall motion helps us to understand the initial stages of star formation. In this paper, we use the IRAM 30-m telescope to make mapping observations of 24 infall sour…
Determining the Hubble Constant with AGN-assisted Black Hole Mergers
Lucas M. B. Alves, Andrew G. Sullivan, Yang Yang +4
Gravitational waves from neutron star mergers have long been considered a promising way to measure the Hubble constant, , which describes the local expansion rate of the unive…
Resolving the Nuclear Radio Emission from M32 with Very Large Array
Sijia Peng, Zhiyuan Li, Loránt O. Sjouwerman +3
The Local Group dwarf elliptical galaxy M32 hosts one of the nearest and most under-luminous super-massive black holes (SMBHs) ever known, offering a rare opportunity to study the…
CHANG-ES XI: Circular Polarization in the Cores of Nearby Galaxies
Judith A Irwin, Richard N. Henriksen, Marek Wezgowiec +18
We detect 5 galaxies in the CHANG-ES (Continuum Halos in Nearby Galaxies -- an EVLA Survey) sample that show circular polarization (CP) at L-band in our high resolution data sets.…
Very Large Array multi-band monitoring observations of M 31*
Yang Yang, Zhiyuan Li, Loránt O. Sjouwerman +2
The Andromeda galaxy (M\,31) hosts one of the nearest and most quiescent super-massive black holes, which provides a rare, but promising opportunity for studying the physics of bla…
Detection of a Compact Nuclear Radio Source in the Local Group Elliptical Galaxy M32
Yang Yang, Zhiyuan Li, Loránt O. Sjouwerman +4
The Local Group compact elliptical galaxy M32 hosts one of the nearest candidate super-massive black holes (SMBHs), which has a previously suggested X-ray counterpart. Based on sen…
