NGC 5486 is an irregular galaxy in the constellation Ursa Major 110 million light-years from Earth. [2]The galaxy is considered a member of the NGC 5485 group (LGG 373), [citation needed] and is near the much larger Pinwheel Galaxy.
Answering a question posed by Lokshtanov (2010), Hartung & Nichterlein (2013) show that the metric dimension decision problem is complete for the parameterized complexity class W[2], implying that a time bound of the form n O(k) as achieved by this naive algorithm is likely optimal and that a fixed-parameter tractable algorithm (for the ...
NGC 5422 is a lenticular galaxy [3] located in the constellation Ursa Major.It was discovered on April 14, 1789, by the astronomer William Herschel. [5]At a distance of about 100 million light-years (30 megaparsecs), NGC 5422 is located within the sparse NGC 5485 group, which is dominated by lenticular galaxies. [3]
It spans a region of 1.7 × 1.2 kpc with an absolute magnitude of −14.8 in the B (blue) band, making it "one of the most impressive GHRs known". This is the only large site in NGC 5398 that is undergoing star formation , and it suggests that NGC 5398 is engaged in some form of interaction .
The luminosity class of NGC 5278 is II. [2] The nucleus of this galaxy presents a burst of star formation (SBNG starburst nucleus galaxies) and it is an active Seyfert 2 type galaxy . In addition, NGC 5278 is possibly a LINER galaxy , a galaxy whose nucleus presents an emission spectrum characterized by broad lines of weakly ionized atoms . [ 3 ]
The locomotives operated from a 1,500 V DC catenary with two pantographs, powering four 1,000 horsepower (750 kW) motors. Each locomotive had over 5,000 metres (16,000 ft) of wire for the series-wound electric motors. The driver would start the engines in series, with only 1 ⁄ 4 voltage applied at 350 A.
NGC 5005 contains a low ionization nuclear emission region (LINER) nucleus. [6] LINER nuclei contain weakly ionized gas. The power source for the LINER emission has been debated extensively, with some researchers suggesting that LINERs are powered by active galactic nuclei that contain supermassive black holes and other researchers suggesting that LINERs are powered by star formation activity.
NGC 5634 is a globular cluster in the constellation Virgo (constellation), located about 82,200 light years (25.2 kiloparsecs) away. [2] NGC 5634 has an apparent magnitude of about 10 [2] and a diameter of 4 or 5 arcminutes. [3] Its Shapley–Sawyer Concentration Class is IV, [1] meaning the cluster shows intermediate rich concentrations. The ...
