In this study, the fundamental stellar atmospheric parameters (Teff, log g, [Fe/H] and [α/Fe]) were derived for low-resolution spectroscopy from LAMOST DR5 with Generative Spectrum…
Harmonic Summing Improves Pulsar Detection Sensitivity: A Probability Analysis
Meng Yu
Practical application of the harmonic summing technique in the power-spectrum analysis for searching pulsars has exhibited the technique's effectiveness. In this paper, theoretical…
Distances of Galactic Supernova Remnants Using Red Clump Stars
S. S. Shan, H. Zhu, W. W. Tian +4
We carry out a project to independently measure the distances of supernova remnants (SNRs) in the first quadrant of the Galaxy. In this project, red clump (RC) stars are used as st…
Radio Morphing: towards a fast computation of the radio signal from air showers
Anne Zilles, Olivier Martineau-Huynh, Kumiko Kotera +6
Over the last years, radio detection has matured to become a competitive method for the detection of air showers. Arrays of thousands of antennas are now envisioned for the detecti…
Meteorological data from KLAWS-2G for an astronomical site survey of Dome A, Antarctica
Yi Hu, Keliang Hu, Zhaohui Shang +8
We present an analysis of meteorological data from the second generation of the Kunlun Automated Weather Station (KLAWS-2G) at Dome A, Antarctica during 2015 and 2016. We find that…
Verifying and Reporting Fast Radio Bursts
Griffin Foster, Aris Karastergiou, Marisa Geyer +6
Fast Radio Bursts (FRBs) are a class of short-duration transients at radio wavelengths with inferred astrophysical origin. The prototypical FRB is a broadband signal that occurs ov…
Visible astro-comb filtered by a passively-stabilized Fabry-Perot cavity
Yuxuan Ma, Fei Meng, Yizhou Liu +4
We demonstrate a compact 29.3 GHz visible astro-comb covering the spectrum from 560nm to 700nm. A 837 MHz Yb:fiber laser frequency comb phase locked to a Rb clock served as the see…
Prospects of Probing the Radio Emission of Lunar UHECRv Events
Amin Aminaei, Linjie Chen, Hamid R. Pourshaghaghi +4
Radio detection of Ultra High Energetic Cosmic Rays and Neutrinos (UHECRv) which hit the Moon has been investigated in recent years. In preparation for near-future lunar science mi…
Studies of Turbulence Dissipation in Taurus Molecular Cloud with Core Velocity Dispersion (CVD)
Lei Qian, Di Li, Yang Gao +2
Turbulence dissipation is an important process affecting the energy balance in molecular clouds, the birth place of stars. Previously, the rate of turbulence dissipation is often e…
Maunakea Spectroscopic Explorer (MSE): a preliminary design of multi-object high resolution spectrograph
Kai Zhang, Yifei Zhou, Zhen Tang +8
The Maunakea Spectroscopic Explorer (MSE) project will transform the CFHT 3.6m optical telescope to a 10m class dedicated multi-object spectroscopic facility, with an ability to me…
An Eigenvector-based Method of Radio Array Calibration and Its Application to the Tianlai Cylinder Pathfinder
Shifan Zuo, Ue-Li Pen, Fengquan Wu +4
We propose an eigenvector-based formalism for the calibration of radio interferometer arrays. In the presence of a strong dominant point source, the complex gains of the array can…
Decompose temporal variations of pulsar dispersion measures
P. F. Wang, J. L. Han
Pulsar dispersion measure (DM) accounts for the total electron content between a pulsar and us. High-precision observations for projects of pulsar timing arrays show temporal DM va…
