Direct observational evidence of the multi-scale, dynamical mass accretion toward a high-mass star forming hub-filament system
Dongting Yang, Hong-Li Liu, Anandmayee Tej +28
There is growing evidence that high-mass star formation and hub-filament systems (HFS) are intricately linked. The gas kinematics along the filaments and the forming high-mass star…
Evidence of high-mass star formation through multi-scale mass accretion in hub-filament-system clouds
Hong-Li Liu, Anandmayee Tej, Tie Liu +30
We present a statistical study of a sample of 17 hub-filament-system (HFS) clouds of high-mass star formation using high-angular resolution (1-2 arcsecond) ALMA 1.3mm and 3mm…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- XII: Fragmentation and multi-scale gas kinematics in protoclusters G12.42+0.50 and G19.88-0.53
Anindya Saha, Anandmayee Tej, Hong-Li Liu +15
We present new continuum and molecular line data from the ALMA Three-millimeter Observations of Massive Star-forming regions (ATOMS) survey for the two protoclusters, G12.42+0.50 a…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- XI. From inflow to infall in hub-filament systems
Jian-Wen Zhou, Tie Liu, Neal J. Evans +37
We investigate the presence of hub-filament systems in a large sample of 146 active proto-clusters, using HCO J=1-0 molecular line data obtained from the ATOMS survey.…
MOA-2019-BLG-008Lb: a new microlensing detection of an object at the planet/brown dwarf boundary
E. Bachelet, Y. Tsapras, Andrew Gould +68
We report on the observations, analysis and interpretation of the microlensing event MOA-2019- BLG-008. The observed anomaly in the photometric light curve is best described throug…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions-IX. A pilot study towards IRDC G034.43+00.24 on multi-scale structures and gas kinematics
Hong-Li Liu, Anandmayee Tej, Tie Liu +21
We present a comprehensive study of the gas kinematics associated with density structures at different spatial scales in the filamentary infrared dark cloud, G034.43+00.24 (G34). T…
ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- V. Hierarchical fragmentation and gas dynamics in IRDC G034.43+00.24
Hong-Li Liu, Anandmayee Tej, Tie Liu +35
We present new 3-mm continuum and molecular lines observations from the ATOMS survey towards the massive protostellar clump, MM1, located in the filamentary infrared dark cloud (IR…
Towards a Network of Faint DA White Dwarfs as High-Precision Spectrophotometric Standards
Gautham Narayan, Tim Axelrod, Jay B. Holberg +8
We present initial results from a program aimed at establishing a network of hot DA white dwarfs to serve as spectrophotometric standards for present and future wide-field surveys.…
The Cepheid Distance to NGC 5236 (M 83) with the VLT
Frank Thim, G. A. Tammann, A. Saha +4
Cepheids have been observed in NGC 5236 (M 83) using the ANTU (UT1) 8.2 meter telescope of the ESO VLT with FORS1. Observations over 34 epochs in V and I have been made between Jan…
Bias Properties of Extragalactic Distance Indicators.XI. Methods to Correct for Observational Selection Bias for RR Lyrae Absolute Magnitudes from Trigonometric Parallaxes Expected from the FAME Astrometric Satellite
Allan Sandage, A. Saha
Please note that this abstract has been shortened from that found in the paper. A brief history is given of the development of the correction for observation selection bias inheren…
