First BISTRO observations of the dark cloud Taurus L1495A-B10: the role of the magnetic field in the earliest stages of low-mass star formation
Derek Ward-Thompson, Janik Karoly, Kate Pattle +155
We present BISTRO Survey 850 μm dust emission polarisation observations of the L1495A-B10 region of the Taurus molecular cloud, taken at the JCMT. We observe a roughly triangular n…
First M87 Event Horizon Telescope Results. I. The Shadow of the Supermassive Black Hole
The Event Horizon Telescope Collaboration
When surrounded by a transparent emission region, black holes are expected to reveal a dark shadow caused by gravitational light bending and photon capture at the event horizon. To…
Korean VLBI Network Calibrator Survey (KVNCS): 1. Source Catalog Of KVN Single Dish Flux Density Measurement In The K And Q Bands
Jeong Ae Lee, Bong Won Sohn, Taehyun Jung +2
We present the catalog of the KVN Calibrator Survey (KVNCS). This first part of the KVNCS is a single dish radio survey conducted at 22 (K band) and 43 GHz (Q band) simultaneously…
Linear Polarization of Class I Methanol Masers in Massive Star-Forming Regions
Ji-hyun Kang, Do-Young Byun, Kee-Tae Kim +3
Class I methanol masers are found to be good tracers of the interaction between outflows from massive young stellar objects with their surrounding media. Although polarization obse…
Interferometric Monitoring of Gamma-ray Bright AGNs I: Results of Single-epoch Multifrequency Observations
Sang-Sung Lee, Kyoaki Wajima, Juan-Carlos Algaba +12
We present results of single-epoch very long baseline interferometry (VLBI) observations of gamma-ray bright active galactic nuclei (AGNs) using the Korean VLBI Network (KVN) at 22…
Spatially Resolved HCN Absorption Features in the Circumnuclear Region of NGC 1052
Satoko Sawada-Satoh, Duk-Gyoo Roh, Se-Jin Oh +7
We present the first VLBI detection of HCN molecular absorption in the nearby active galactic nucleus NGC 1052. Utilizing the 1 milliarcsecond resolution achieved by the Korean VLB…
