During 1996 and 1997, the Canary Island Observatories' `International Time' project on Barred Galaxies obtained photometric images in broad- and narrow-band...
The Baryonic Matter at Supercluster Scales: The Case of Corona Borealis Supercluster
In a recent survey for baryonic matter at large scales in the Corona Borealis Supercluster, using the Sunyaev-Zeldovich (SZ) effect, it has been found SZ...
The cores of neutron stars harbor the highest matter densities known to occur in nature, up to several times the densities in atomic nuclei. Similarly, magnetic...
It is now clear that central star binarity plays a key role in the formation and evolution of planetary nebulae, with a significant fraction playing host to...
The binary central stars of PNe with the shortest orbital period
Close binarity can play a significant role in the shaping of planetary nebulae (PNe) as the system evolves through the common-envelope phase. We present the...
