The relationship between changes in the Economic Sentiment Indicator and real GDP growth: a time-varying coefficient approach

The aim of this paper is to capture the time-varying effects of the relationship between changes in the Economic Sentiment Indicator (ESI) and economic growth. We use penalized regression splines to estimate the different point effects over time. Evidence from six European countries supports the idea that the elasticity of the ESI is time-varying.Economic Sentiment Indicator; Real GDP Growth; Thin Plate Regression Splines; Time-Varying Coefficient Model

Observing the Galactic Plane with the Cherenkov Telescope Array

The Cherenkov Telescope Array is a next generation ground-based gamma-ray observatory de- signed to detect photons in the 20 GeV to 300 TeV energy range. With a sensitivity improvement of up to one order of magnitude on the entire energy range with respect to currently operating facilities, coupled with significantly better angular resolution, the array will be used to address many open questions in high-energy astrophysics. In addition, CTA will explore the ultra-high energy (E >50 TeV) window with great sensitivity for the first time. CTA is expected to reveal a detailed picture of the Galactic plane at the highest energies, and to discover around one hundred new supernova remnants and many hundreds of pulsar wind nebulae, according to current population estimates. The ability of the observatory to resolve such a large number of Galactic sources is one of the challenges to be faced. In this paper, we will present the first simulated scan of the Galactic plane with a realistic observation strategy, with particular attention to the potential source confusion. We will also present prospects for morphological studies of extended sources, such as the young SNR RX J1713.7-39.Comment: All CTA contributions at arXiv:1709.03483; PoS 35th International Cosmic Ray Conference ICRC2017 Busan, Kore
