Galaxy and Mass Assembly (GAMA): The Weak Environmental Dependence of Quasar Activity at 0.1<z<0.35

Clare F. Wethers, Nischal Acharya, Roberto De Propris +13

Understanding the connection between nuclear activity and galaxy environment remains critical in constraining models of galaxy evolution. By exploiting extensive catalogued data fr…

K2-99 revisited: a non-inflated warm Jupiter, and a temperate giant planet on a 522-d orbit around a subgiant

A. M. S. Smith, S. N. Breton, Sz. Csizmadia +29

We report new photometric and spectroscopic observations of the K2-99 planetary system. Asteroseismic analysis of the short-cadence light curve from K2's Campaign 17 allows us to r…

BASS XXIX: The near-infrared view of the BLR: the effects of obscuration in BLR characterisation

Ricci F., Treister E., Bauer F. E. +24

Virial black hole mass () determination directly involves knowing the broad line region (BLR) clouds velocity distribution, their distance from the central supermassive bla…

Stellar populations in local AGNs: evidence for enhanced star formation in the inner 100pc

L. G. Dahmer-Hahn, R. Riffel, A. Rodríguez-Ardila +7

In modern models and simulations of galactic evolution, the star formation in massive galaxies is regulated by an ad hoc active galactic nuclei (AGN) feedback process. However, the…

Faint objects in motion: the new frontier of high precision astrometry

Fabien Malbet, Céline Boehm, Alberto Krone-Martins +83

Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…

Analysis of Early Science observations with the CHaracterising ExOPlanets Satellite (CHEOPS) using pycheops

P. F. L. Maxted, D. Ehrenreich, T. G. Wilson +77

CHEOPS(CHaracterising ExOPlanet Satellite) is an ESA S-class mission that observes bright stars at high cadence from low-Earth orbit. The main aim of the mission is to characterize…
