Improved upper limits on the 21 cm signal power spectrum of neutral hydrogen at z ≈ 9.1 from LOFAR
Galaxies, Journal, Large-scale structure
A new upper limit on the 21 cm signal power spectrum at a redshift of $z \approx 9.1$ is presented, based on 141 h of data obtained with the Low-Frequency Array (LOFAR). The analysis includes significant improvements in spectrally smooth…

The 1.28 GHz MeerKAT DEEP2 Image
Journal, Large-scale structure, Stars
We present the confusion-limited 1.28 GHz MeerKAT DEEP2 image covering one $\theta_b\approx 68'$ FWHM primary-beam area with $\theta=7.6^{''}$ FWHM resolution and $\sigma_n=0.55\pm 0.01$ $\mu$Jy beam$^{-1}$ rms noise. Its J2000 center position…
