Teleskop Be- Stens Geeignet für Astronomie Nr. 13 Zeitschrift der Vereinigung der Sternfreunde e.V. / VdS Spektroskopie Beobachterforum ISSN 1615 - 0880 www.vds-astro.de I/ 2004 Astronomik Handbuch für Sternfreunde Filter für die Astronomie Astronomik Filter sind eine neue Spezialentwicklung für die Astronomie. Mit diesen Filtern gibt es erstmals hochwertige und dennoch günstige Interferenzfilter für die CCD Astronomie und die visuelle Beobachtung. Die Astronomik Filter werden nach einem neuartigen Verfahren hersgestellt: Die Transmissionskurven werden fast mit mathematischer Genauigkeit ein- gehalten und wir haben reale Transmissionen bis zu 99,5% gemessen. Die Astronomik Filter sind nicht mit den bekannten Filtern aus Japan oder den USA vergleichbar: Die Schichten sind vollkommen dicht und feuchtig- keitsunempfindlich: Astronomik Filter verändern sich nicht im Laufe der Jahre, sondern behalten ihre Transmissionskurve "ewig". Weiterhin sind die Schichten so hart, daß kein versehentliches Verkratzen möglich ist. Sie müssen schon mutwillig mit Schleifpapier auf die Filter losgehen, um kleine Kratzer zu erzeugen. Astronomik Filter müssen Sie nicht wie ein ro- hes Ei behandeln und müssen nicht peinlichst auf trockene Lagerung ach- ten. Astronomik Filter sind für den harten Einsatz an Ihrem Teleskop be- stens geeignet.

In fact, it could be argued that WWII inventions marked the inception of the modern technological era1.

Jansky (c. 1933) Around 1930, there was increasing interest in the use of radio frequencies for communication. One of the main players, the Bell Telephone Laboratories in New Jersey, asked their research engineer, Karl Jansky (Figure 1), to investigate the inter- ference environment in the “short-wave” band around 20 MHz.

  • Radio Astronomy
    Theme 8: Beyond the Visible I: radio astronomy Until the turn of the 17th century, astronomical observations relied on the naked eye. For 250 years after this, although astronomical instrumentation made great strides, the radiation being detected was still essentially confined to visible light (Herschel discovered infrared radiation in 1800, and the advent of photography opened up the near ultraviolet, but these had little practical significance). This changed dramatically in the mid-20th century with the advent of radio astronomy. 8.1 Early work: Jansky and Reber The atmosphere is transparent to visible light, but opaque to many other wavelengths. The only other clear “window” of transparency lies in the radio region, between 1 mm and 30 m wavelength. One might expect that the astronomical community would deliberately plan to explore this region, but in fact radio astronomy was born almost accidentally, with little if any involvement of professional astronomers. Karl Jansky (1905−50) was a radio engineer at Bell Telephone. In 1932, while studying the cause of interference on the transatlantic radio-telephone link, he discovered that part of the interference had a periodicity of one sidereal day (23h 56m), and must therefore be coming from an extraterrestrial source. By considering the time at which the interference occurred, Jansky identified the source as the Milky Way. This interesting finding was completely ignored by professional astronomers, and was followed up only by the radio engineer and amateur astronomer Grote Reber (1911−2002). Reber built a modern-looking paraboloid antenna and constructed maps of the radio sky, which also failed to attract significant professional attention.

  • Kinematic and Emission Analysis of the Relativistic Jet in the Blazar B1551+130 Using VLBI Data
    Kinematic and Emission Analysis of the Relativistic Jet in the Blazar B1551+130 using VLBI Data Shaun Julian Nicol MSci Project Imperial College London Host Institute: Supervisor: Universitat de Val`encia Prof. Eduardo Ros Ibarra June 2012 Abstract Very Long Baseline Interferometry (VLBI) allows the most energetic structures in our universe to be observed with sub-milliarcsecond resolution (parsecs at cosmological distances). These methods are particularly effective in observing the relativistic jets extending from the black hole region of active galactic nu- clei (AGN). Six epochs of VLBI data from the MOJAVE 2 cm survey taken between June 2009 and April 2012 are used to carry out the kinematic analysis of the relativistic jet in the flat spectrum radio quasar B1551+130 with red- shift z = 1:308. The apparent velocities of areas of enhanced radio emission, or `knots', in the jet, calculated through the model fitting technique, are pre- sented along with images of the source obtained through the hybrid mapping process. Superluminal velocities for the `knots' are observed with the highest apparent velocity being 10.21.8c. From this maximum velocity, the viewing angle of 5.6◦ 1◦ is derived, agreeing with the classification of the source as a FSRQ. An estimate of the luminosity Doppler boosting factor gives a value of order 102. Two jet features are observed with negative superluminal velocities, the most significant being the region closest to the base or `core' of the jet ob- served with a velocity of {10.62.7c. The flux of this region undergoes a large increase during the most recent observations, between mid 2011 and mid 2012.

Introduction An important window to the Universe was opened in 1933 when Karl Jansky discovered serendipitously at the Bell Telephone Laboratories that radio waves were being emitted towards the direction of our Galaxy [1]. Jansky could not pursue investigations concerning this discovery, as the Lab- oratory was devoted to work primarily in the field of communications. This discovery was also not followed by any astronomical institute, although a few astronomers did make proposals. However, a young electronics engi- neer, Grote Reber, after reading Jansky’s papers, decided to build an inno- vative parabolic dish of 30 ft. diameter in his backyard in 1935 and made the first radio map of the Galaxy in 1940 [2]. The rapid developments of radars during World War II led to the dis- covery of radio waves from the Sun by Hey in 1942 at metre wavelengths in UK and independently by Southworth in 1942 at cm wavelengths in USA. Due to the secrecy of the radar equipment during the War, those re- sults were published by Southworth only in 1945 [3] and by Hey in 1946 [4]. Reber reported detection of radio waves from the Sun in 1944 [5]. These results were noted by several groups soon after the War and led to intensive developments in the new field of radio astronomy.

Lunar mansion names in South-West China: An etymological reconstruction of ancestral astronomical designations in Moso, Pumi, and Yi cultures compared with Chinese and Tibetan contexts Abstract: The present study aims at an etymological reconstruction of lunar mansion designations of the Moso, Pumi, and Yi people from South-West China. Those lunar mansions are generally named after animals. A systematic examination on these astronomical names reveals frequent borrowing processes among these cultures, extended to Tibetan and Chinese contexts. Three patterns of direct borrowing of the lunar mansion names can be highlighted in addition to compatible morphological structures in some designation. This comparative research also provides innovative 114 XU DUODUO solutions to several issues still unsolved from the current studies on lunar mansions focused on specific ethnic groups.
