RICO: A New Approach for Fast and Accurate Representation of the Cosmological Recombination History
We present RICO, a code designed to compute the ionization fraction of the universe during the epoch of hydrogen and helium recombination with an unprecedented...
Book Review: Tombs, Temples and Their Orientations : A new Perspective on Mediterranean Prehistory, by M. Hoskin (Ocarina Books, bognor Regis, 2001; distributed...
We present a search for rings or arcs in the haloes of planetary nebulae (PNe). We discovered such structures in eight PNe, tripling the sample of PNe with...
Rise of the Titans: A Dusty, Hyper-luminous “870 μm Riser” Galaxy at z ∼ 6
We report the detection of ADFS-27, a dusty, starbursting major merger at a redshift of z = 5.655, using the Atacama Large Millimeter/submillimeter Array (ALMA)...
Rise of the Titans: Gas Excitation and Feedback in a Binary Hyperluminous Dusty Starburst Galaxy at z ∼ 6
We report new observations toward the hyperluminous dusty starbursting major merger ADFS-27 (z = 5.655), using the Australia Telescope Compact Array (ATCA) and...
Rise times of horizontal magnetic flux tubes in the convection zone of the sun
Solutions of the equations describing the motion of a straight horizontal magnetic flux tube in the convection zone of the sun including inertial term and...
RMS asymmetry: a robust metric of galaxy shapes in images with varied depth and resolution
Structural disturbances, such as galaxy mergers or instabilities, are key candidates for driving galaxy evolution, so it is important to detect and quantify...
Roadmap on carbon molecular nanostructures in space
In this roadmap article, we consider the main challenges and recent breakthroughs in understanding the role of carbon molecular nanostructures in space and...
