Euclid: The reduced shear approximation and magnification bias for Stage IV cosmic shear experiments
A. C. Deshpande, T. D. Kitching, V. F. Cardone +69
Stage IV weak lensing experiments will offer more than an order of magnitude leap in precision. We must therefore ensure that our analyses remain accurate in this new era. Accordin…
On the pressure equilibrium and timescales in the scale free convection theory
Stefano Pasetto, Cesare Chiosi, Mark Cropper +2
Convection is one of the fundamental energy transport processes in physics and astrophysics, and its description is central to allstellar models. In the context of stellar astrophy…
Chronos: A NIR spectroscopic survey to target the most important phases of galaxy evolution across cosmic time
I. Ferreras, M. Cropper, R. Sharples +15
(Abridged summary) Responding to ESA's Voyage 2050 call to define the long-term plan for the future space missions that will address the astrophysics science questions during the 2…
Astro2020 Activity, Project of State of the Profession Consideration (APC) White Paper: All-Sky Near Infrared Space Astrometry. State of the Profession Considerations: Development of Scanning NIR Detectors for Astronomy
David Hobbs, Christopher Leitz, Jo Bartlett +11
Gaia is a revolutionary space mission developed by ESA and is delivering 5 parameter astrometry, photometry and radial velocities over the whole sky with astrometric accuracies dow…
Propagating Residual Biases in Cosmic Shear Power Spectra
T. D. Kitching, P. Paykari, H. Hoekstra +1
In this paper we derive a full expression for the propagation of multiplicative and additive shape measurement biases into the cosmic shear power spectrum. In doing so we identify…
Full orbital solution for the binary system in the northern Galactic disc microlensing event Gaia16aye
Łukasz Wyrzykowski, P. Mróz, K. A. Rybicki +182
Gaia16aye was a binary microlensing event discovered in the direction towards the northern Galactic disc and was one of the first microlensing events detected and alerted to by the…
