First frequency phase transfer from the 3 mm to the 1 mm band on an Earth-sized baseline
Sara Issaoun, Dominic W. Pesce, María J. Rioja +33
Frequency Phase Transfer (FPT) is a technique designed to increase coherence and sensitivity in radio interferometry by making use of the non-dispersive nature of the troposphere t…
CONCERTO: Instrument model of Fourier transform spectroscopy, white-noise components
Alessandro Fasano, Peter Ade, Manuel Aravena +34
Modern astrophysics relies on intricate instrument setups to meet the demands of sensitivity, sky coverage, and multi-channel observations. An example is the CONCERTO project, empl…
CONCERTO: instrument and status
Alessandro Fasano, Peter Ade, Manuel Aravena +36
CONCERTO (CarbON CII line in post-rEionization and ReionizaTiOn) is a low-resolution Fourier transform spectrometer dedicated to the study of star-forming galaxies and clusters of…
Geometry of Fanning Curves in Divisible Grassmannians
Carlos E. Durán, Cíntia R. de A. Peixoto
We study the geometry of fanning curves in the Grassmann manifold of n-dimensional subspaces of ; we construct a complete system of invariants which solve the cong…
Flat Sections and Non-negative Curvature in Pullback Bundles
C. Durán, L. D. Sperança
We give a geometric obstruction to the non-negativity of the sectional curvature in the total spaces of certain Riemannian submersions with totally geodesic fibers; applications of…
Equivariant homotopy and deformations of diffeomorphisms
C. E. Durán, A. Rigas
We present a way of constructing and deforming diffeomorphisms of manifolds endowed with a Lie group action. This is applied to the study of exotic diffeomorphisms and involutions…
