New dwarf galaxy candidates in the sphere of influence of the Sombrero galaxy
We report the discovery of 40 new satellite dwarf galaxy candidates in the sphere of influence of the Sombrero Galaxy (M104), the most luminous galaxy in the Local Volume. Using the Subaru Hyper Suprime-Cam, we surveyed 14.4 deg(2) of its surroundings, ext ...
Oxford2023The extended stellar halo' of the Ursa Minor dwarf galaxy
Stellar candidates in the Ursa Minor (UMi) dwarf galaxy have been found using a new Bayesian algorithm applied to Gaia EDR3 data. Five of these targets are located in the extreme outskirts of UMi, from similar to 5 to 12 elliptical half-light radii (r h), ...
OXFORD UNIV PRESS2023Generation of OAM-carrying space-time wave packets with time-dependent beam radii using a coherent combination of multiple LG modes on multiple frequencies
Tobias Kippenberg, Maxim Karpov, Zhe Zhao, Hao Song, Xinzhou Su
Space-time (ST) wave packets, in which spatial and temporal characteristics are coupled, have gained attention due to their unique propagation characteristics, such as propagation invariance and tunable group velocity in addition to their potential ability ...
Optica Publishing Group2022The eta Aquilae System: Radial Velocities and Astrometry in Search of eta Aql B
The classical Cepheid eta Aql was not included in past Leavitt Law work because of a presumed complicating orbit due to a known B9.8V companion. To determine the orbit of eta Aql B, we analyze a significant number of radial velocity (RV) measurements from ...
2022The Pristine dwarf galaxy survey - IV. Probing the outskirts of the dwarf galaxy Bootes I
Pascale Jablonka, Nicolas Lawrence Etienne Longeard, Romain Ely Roland Lucchesi
We present a new spectroscopic study of the dwarf galaxy Bootes I (Boo I) with data from the Anglo-Australian Telescope and its AAOmega spectrograph together with the Two Degree Field multi-object system. We observed 36 high-probability Boo I stars selecte ...
OXFORD UNIV PRESS2022Concordia: A musical XR instrument for playing the solar system
Kepler Concordia, a new scientific and musical instrument enabling players to explore the solar system and other data within immersive extended-reality (XR) platforms, is being designed by a diverse team of musicians, artists, scientists and engineers usin ...
ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD2020Comparison of gait characteristics between clinical and daily life settings in children with cerebral palsy
Kamiar Aminian, Anisoara Ionescu, Lena Carcreff, Stéphane Armand
Gait assessments in standardized settings, as part of the clinical follow-up of children with cerebral palsy (CP), may not represent gait in daily life. This study aimed at comparing gait characteristics in laboratory and real life settings on the basis of ...
NATURE PUBLISHING GROUP2020A microphotonic astrocomb
Tobias Kippenberg, Michael Wolfgang Geiselmann, Junqiu Liu, Tobias Herr, Miles Henry Anderson, Stefan Kundermann
Earth-like planets, dark energy and variability of fundamental physical constants can be discovered by observing wavelength shifts in the optical spectra of astronomical objects(1-5). These wavelength shifts are so tiny that exquisitely accurate and precis ...
NATURE PUBLISHING GROUP2019Flexible support and enhanced groove geometries for gas lubricated bearings
Gas lubricated Herringbone-Grooved Journal Bearings (HGJB) are a promising solution to support high-speed rotors in oil-free turbo-machinery due to their compactness, relatively low losses, no need for lubrication and low wear.
Gas lubricated bearings, how ...
EPFL2019NeuroMorph: A Software Toolset for 3D Analysis of Neurite Morphology and Connectivity
Graham Knott, Jérôme Blanc, Anne Alison Jorstad
The geometries of axons, dendrites and their synaptic connections provide important information about their functional properties. These can be collected directly from measurements made on serial electron microscopy images. However, manual and automated se ...
