The MeerKAT Radio Telescope

open access: yes, 2018
This paper is a high-level description of the development, implementation and initial testing of the MeerKAT radio telescope and its subsystems. The rationale for the design and technology choices is presented in the context of the requirements of the ...

Kinematics and physical conditions of H I in nearby radio sources. The last survey of the old Westerbork Synthesis Radio Telescope [PDF]

open access: yes, 2017
We present an analysis of the properties of neutral hydrogen (H I) in 248 nearby (0.02 30 mJy and for which optical spectroscopy is available. The observations were carried out with the Westerbork Synthesis Radio Telescope as the last large project ...

Sardinia Radio Telescope observations of Abell 194 [PDF]

open access: yesAstronomy & Astrophysics, 2017
Aims. We study the intra-cluster magnetic field in the poor galaxy cluster Abell 194 by complementing radio data, at different frequencies, with data in the optical and X-ray bands.Methods. We analyzed new total intensity and polarization observations of

Response of the Effelsberg 100m radio telescope to signals in the near-field at 24 GHz [PDF]

open access: yesAdvances in Radio Science, 2003
Short range radar (SRR) for cars has been proposed to operate over 5 GHz of bandwidth at the 24 GHz ISM band. To estimate the level of interference from these devices on radio telescopes, the near-field antenna pattern has to be known.

Search for possible exomoons with FAST telescope

open access: yes, 2017
Our knowledge of the Solar System, encourages us to beleive that we might expect exomoons to be present around some of the known exoplanets. With present hardware and existing optical astronomy methods we shall not be able to find exomoons at least 10 ...

Infrared-radio-follow-up observations for detection of the magnetic radio emission of extra solar planets: a new window to detect exoplanets

open access: yesFrontiers in Astronomy and Space Sciences
There are several methods for indirectly detecting exoplanets, such as transit, radial velocity, astrometry, and the conventional gravitational microlensing approach.

The new era of large paraboloid antennas: the life of Prof. Dr. Otto Hachenberg [PDF]

open access: yesAdvances in Radio Science, 2003
Seldom does a scientist get an opportunity in his lifetime to build an instrument that remains unchallenged as the world’s no. 1 for 30 years. The Effelsberg 100- m radio telescope, constructed under the direction of Prof. Dr.

Orbit Determination of Resident Space Objects Using the P-Band Mono-Beam Receiver of the Sardinia Radio Telescope

open access: yesApplied Sciences, 2019
The population of space debris in near-Earth space is continuously growing and it represents a serious problem for active satellites and spacecraft. A performant ground-based and space-based network of sensors is necessary for space surveillance and ...

CHIME FRB: An application of FFT beamforming for a radio telescope [PDF]

open access: yesURSI General Assembly and Scientific Symposium, 2017
We have developed FFT beamforming techniques for the CHIME radio telescope, to search for and localize the astrophysical signals from Fast Radio Bursts (FRBs) over a large instantaneous field-of-view (FOV) while maintaining the full angular resolution of
