One of the primary science goals of the next generation of hard x-ray timing instruments is to
determine the equation of state of matter at supranuclear densities inside neutron stars by …

Despite its importance to our understanding of physics at supranuclear densities, the
equation of state (EoS) of matter deep within neutron stars remains poorly understood …

Understanding the formation and evolution of the first stars and galaxies represents one of
the most exciting frontiers in astronomy. Since the universe was filled with hydrogen atoms …

ABSTRACT A new upper limit on the 21 cm signal power spectrum at a redshift of z≈ 9.1 is
presented, based on 141 h of data obtained with the Low-Frequency Array (LOFAR). 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 …

ABSTRACT The Large-aperture Experiment to Detect the Dark Age (LEDA) was designed to
detect the predicted O (100) mK sky-averaged absorption of the cosmic microwave …

The early star-forming Universe is still poorly constrained, with the properties of high-redshift
stars, the first heating sources and reionization highly uncertain. This leaves observers …

We present the HI emission project within the MIGHTEE survey, currently being carried out
with the newly commissioned MeerKAT radio telescope. This is one of the first deep, blind …

Abstract The CO Mapping Array Project (COMAP) aims to use line-intensity mapping of
carbon monoxide (CO) to trace the distribution and global properties of galaxies over cosmic …

The 21 cm transition of neutral hydrogen is opening an observational window into the
Cosmic Dawn of the universe—the epoch of first star formation. We use 28 hr of data from …
