Line-intensity mapping (LIM) is an emerging approach to survey the Universe, using
relatively low-aperture instruments to scan large portions of the sky and collect the total …

The ordering of the neutrino masses is a crucial input for a deep understanding of flavor
physics, and its determination may provide the key to establish the relationship among the …

The Square Kilometre Array (SKA) is a planned large radio interferometer designed to
operate over a wide range of frequencies, and with an order of magnitude greater sensitivity …

The redshifted 21 cm line is an emerging tool in cosmology, in principle permitting three-
dimensional surveys of our universe that reach unprecedentedly large volumes, previously …

The accelerating expansion of the universe is the most surprising cosmological discovery in
many decades, implying that the universe is dominated by some form of “dark energy” with …

We present a detection of correlated clustering between MeerKAT radio intensity maps and
galaxies from the WiggleZ Dark Energy Survey. We find a 7.7 σ detection of the cross …

Imaging the Universe during the first hundreds of millions of years remains one of the
exciting challenges facing modern cosmology. Observations of the redshifted 21 cm line of …

We present a framework for forecasting cosmological constraints from future neutral
hydrogen intensity mapping experiments at low to intermediate redshifts. In the process, we …

Current and upcoming radio telescopes will map the spatial distribution of cosmic neutral
hydrogen (H i) through its 21 cm emission. In order to extract the maximum information from …

We present Fisher matrix projections for future cosmological parameter measurements,
including neutrino masses, Dark Energy, curvature, modified gravity, the inflationary …
