In the second half of February the impending Giotto encounter of 13 March concentrated our minds on what the encounter might reveal. As an outcome, we issued a fairly widely circulated preprint with the title Some Predictions on the Nature of Comet Halley, (1 March, 1996, Cardiff Series 121) whose contents were reported in the issue of the Times for 12 March. This publication in the Times was fortunate for us, because it appeared indisputably ahead of the encounter, whereas a contemporaneous submission to the Royal Astronomical Society has suffered long delays to acceptance on advice to the Society from two persons of unknown identities.
Many advances that have improved the robustness and efficiency of deep reinforcement learning (RL) algorithms can, in one way or another, be understood as introducing additional objectives, or constraints, in the policy optimization step. This includ
Intrinsic alignments (IAs) of galaxies are an important contaminant for cosmic shear studies, but the modelling is complicated by the dependence of the signal on the source galaxy sample. In this paper, we use the halo model formalism to capture this
We present a novel formalism to describe the $in$ $vacuo$ conversion between polarization states of propagating radiation, also known as generalized Faraday effect (GFE), in a cosmological context. Thinking of GFE as a potential tracer of new, isotro
In the context of a classroom lesson, concepts must be visualized and organized in many ways depending on the needs of the teacher and students. Traditional presentation media such as the blackboard or electronic whiteboard allow for static hand-draw
We summarize the principles and fundamental ingredients of evolutionary synthesis models, which are stellar evolution, stellar atmospheres, the IMF, star-formation histories, nebular emission, and also attenuation from the ISM and IGM. The chapter fo
