21 cm Intensity Mapping with the DSA-2000
The Astrophysical JournalLine-intensity mapping is a promising probe of the Universe’s large-scale structure. We explore the sensitivity of the DSA-2000, a forthcoming array consisting of over 2000 dishes, to the statistical power spectrum of neutral hydrogen’s 21 cm emission ...

Highly sensitive atomic based MW interferometry
Scientific Reports, 2018 We theoretically study a scheme to develop an atomic based micro-wave (MW) interferometry using the Rydberg states in Rb. Unlike the traditional MW interferometry, this scheme is not based upon the electrical circuits, hence the sensitivity of the phase ...

Designing a radio-interferometric array of Yagi-Uda antennas with spectral window centre at 400 MHz
Revista Técnica de la Facultad de Ingeniería, 2010 It is well known that the observation of celestial bodies through the use of radioastronomic devices has, generally speaking, important advantages in comparison to traditional studies concerning the visual spectrum. Moreover, radio-interferometry gives

Accelerating the CLEAN algorithm of radio interferometry with convex optimization
Astronomy & AstrophysicsContext. In radio interferometry, images are recovered from incompletely sampled Fourier datasets. The de facto standard algorithm, the Cotton–Schwab CLEAN, iteratively switches between computing a deconvolution (minor loop) and subtracting the model ...

Antennas and Receivers in Radio Interferometry
, 2016 The primary antenna elements and receivers are two of the most important components in a synthesis telescope. Together they are responsible for locking onto an astronomical source in both direction and frequency, capturing its radiation, and converting it into signals suitable for digitization and correlation. The properties and performance of antennas

Aliasing from Galactic Plane Setting in Widefield Radio Interferometry
The Astrophysical JournalMeasurements with widefield radio interferometers often include the near-infinite gradient between the sky and the horizon. This causes aliasing inherent to the measurement itself and is purely a consequence of the Fourier basis.
