Example 2: Figure 8 (90 Kbytes) shows an image of M31. While this is not a particularly spectacular image of M31 it is nevertheless unique as it was taken in a suburban backyard using a Lynxx CCD camera. The exposure is unfiltered. ... The image scale in this system is 41 arcseconds per pixel which yields a total field size of 2.2 x 1.9 square degrees. At this pixel resolution M32 blends into the light of M31, although NGC 205 (marked with a red arrow) is plainly visible. ... Page 6 . ...

Let K be a global field. ... The real number $\gamma_K = c_0/c_{-1}$ is called the Euler-Kronecker constant of the field $K$. In the article of Yasutaka Ihara "On the Euler-Kronecker constants of global fields and primes with small norms" the lower bound $\gamma_K\ge-\log\sqrt{|d|}$ is obtained, where $d$ is the discriminant of the field $K$. In my talk I will prove the lower bound $\gamma_K\ge -\left(1-\frac{\sqrt{5}}{5}\right) \log\sqrt{|d|}$. ...

We present a catalogue of galaxies for which spatially resolved data on their internal kinematics have been published; there is no apriori restriction regarding their morphological type. The catalogue lists the references to the articles where the data are published, as well as a coded description of these data: observed emission (E) or absorption (A) data, optical (O) or radio (R) data, velocity (V) or velocity dispersion (D), radial profile (1) or 2D field (2). ...
