A novel radio imaging method for physical spectral index modelling
E. Ceccotti, A. R. Offringa, L. V. E. Koopmans +9
We present a new method, called "forced-spectrum fitting", for physically-based spectral modelling of radio sources during deconvolution. This improves upon current common deconvol…
Retrieving the 21-cm signal from the Epoch of Reionization with learnt Gaussian process kernels
Florent G. Mertens, Jérôme Bobin, Isabella P. Carucci
Direct detection of the Cosmic Dawn and Epoch of Reionization via the redshifted 21-cm line of neutral Hydrogen will have unprecedented implications for studying structure formatio…
Studying the Multi-frequency Angular Power Spectrum of the Cosmic Dawn 21-cm Signal
Abinash Kumar Shaw, Raghunath Ghara, Saleem Zaroubi +5
The light-cone (LC) anisotropy arises due to cosmic evolution of the cosmic dawn 21-cm signal along the line-of-sight (LoS) axis of the observation volume. The LC effect makes the…
Accurate modelling of the Lyman- coupling for the 21-cm signal, observability with NenuFAR and SKA
Benoit Semelin, Romain Mériot, Florent Mertens +6
The measurement of the cm signal from the Cosmic Dawn is a major goal for several existing and upcoming radio interferometers such as NenuFAR and the SKA. During this era befo…
Observations of the Structure and Dynamics of the Inner M87 Jet
R. Craig Walker, Philip E. Hardee, Fred Davies +4
M87 is the best source in which to study a jet at high resolution in gravitational units because it has a very high mass black hole and is nearby. The angular size of the black hol…
Kinematics of the jet in M87 on scales of 100 -- 1000 Schwarzschild radii
F. Mertens, A. P. Lobanov, R. C. Walker +1
Very long baseline interferometry (VLBI) imaging of radio emission from extragalactic jets provides a unique probe of physical mechanisms governing the launching, acceleration, and…
