The GRAVITY instrument was primarily conceived for imaging and astrometry of the Galactic centre. However, its sensitivity and astrometric capabilities have also enabled interferometry to reach a new domain of astrophysics: exoplanetology. In March 2019, the GRAVITY collaboration published the first spectrum and astrometry of an exoplanet obtained by optical interferometry. In this article, we show how this observation is paving the way to even more exciting discoveries — finding new planets, and characterising their atmospheres.

The presence of strong absorption lines in the atmospheric transmission spectrum affects spectroscopic observations, in particular those in the nearand mid-infrared. Therefore, there is the need to correct scientific observations for this effect, a process known as telluric correction. The use of a detailed model of the atmospheric transmission spectrum brings several advantages over the method of empirically deriving corrections using observations of a telluric standard star. In this paper, we discuss and compare the two methods applied to K-band Multi-Object Spectrograph (KMOS) observations and show the improvements in the quality of the final products obtained by implementing the modelling technique offered by the ESO molecfit sky tool.

In April 2019, the Event Horizon Telescope (EHT) collaboration revealed the first image of the candidate super- massive black hole (SMBH) at the centre of the giant elliptical galaxy Messier 87 (M87). This event-horizon-scale image shows a ring of glowing plasma with a dark patch at the centre, which is interpreted as the shadow of the black hole. This breakthrough result, which represents a powerful confirmation of Einstein’s theory of gravity, or general relativity, was made possible by assembling a global network of radio telescopes operating at millimetre wavelengths that for the first time included the Atacama Large Millimeter/submillimeter Array (ALMA). The addition of ALMA as an anchor station has enabled a giant leap forward by increasing the sensitivity limits of the EHT by an order of magnitude, effectively turning it into an imaging array. The published image demonstrates that it is now possible to directly study the event horizon shadows of SMBHs via electromagnetic radiation, thereby transforming this elusive frontier from a mathematical concept into an astrophysical reality. The expansion of the array over the next few years will include new stations on different continents — and eventually satellites in space. This will provide progressively sharper and higher-fidelity images of SMBH candidates, and potentially even movies of the hot plasma orbiting around SMBHs. These improvements will shed light on the processes of black hole accretion and jet formation on event-horizon scales, thereby enabling more precise tests of general relativity in the truly strong field regime.

This theme of this article is the audiences segmentation by local television in Central Java. This study is motivated by the large amount of number of local television stations that have sprung up, as the digital era progresses. This study uses qualitative descriptive approach with the sample of five television stations, namely Banyumas TV, Semarang TV, TVKU Semarang, Simpang5 TV Pati, and also Ratih TV Kebumen. The target of the audiences segmentation demographically is the people aged 30 years and above, except TVKU Semarang, namely teenagers and students aged 15-25 years. The development in the digital era is now an opportunity to maintain the existence of local television by doing convergence of digital media. The concept of ‘Think Global Act Local’ is the opposite in the local television industry to become ‘Think Local Act Global’, for the broadcasting world if they still want to exist in the digital media.
本文的主题是中爪哇地方电视台的受众细分。这项研究的动机是随着数字时代的发展,大量的地方电视台如雨后春笋般涌现。本研究以Banyumas TV、三宝垄TV、TVKU三宝垄TV、Simpang5 TV patti和Ratih TV Kebumen五家电视台为样本,采用定性描述的方法。受众细分的人口学目标是30岁及以上的人群,TVKU三宝郎除外,即15-25岁的青少年和学生。数字时代的发展给地方电视台提供了一个机会,可以通过数字媒体的融合来维持地方电视台的存在。“思考全球,行动本地化”的概念在地方电视行业是相反的,如果广播界仍然想在数字媒体中存在,就变成“思考本地,行动全球化”。
