A New H I Ring : LGG 138
A complete ring of neutral hydrogen gas (HI) in the LGG 138 group of galaxies has been found. The HI mass of the ring is greater than 10 h−2 75 M ̄, and the gas appears to be rotating with a projected circular speed of ∼200 km s−1. Two bright galaxies are enclosed by the ring, both having radial velocities consistent with membership of the group. Faint stellar emission extends to the radial dist...
متن کاملStudy on the new graph constructed by a commutative ring
Let R be a commutative ring and G(R) be a graph with vertices as proper andnon-trivial ideals of R. Two distinct vertices I and J are said to be adjacentif and only if I + J = R. In this paper we study a graph constructed froma subgraph G(R)Δ(R) of G(R) which consists of all ideals I of R such thatI Δ J(R), where J(R) denotes the Jacobson radical of R. In this paper westudy about the relation b...
متن کاملA New Solution to Analysis of CMOS Ring Oscillators
New equations are proposed for frequency and amplitude of a ring oscillator. The method is general enough to be used for all types of delay stages. Using exact largesignal circuit analysis, closed form equations for estimating the frequency and amplitude of a high frequency ring oscillator are derived as an example. The method takes into account the effect of various parasitic capacitors to...
متن کاملGalactic Recycling: the Hi Ring around Ngc 1533
We report the discovery of a new Hi ring around the S0 galaxy NGC 1533. The ring orbits at a radius of 35 kpc, well outside the optical extent of the galaxy. We have conducted N-body/SPH numerical simulations to show this Hi ring could be the merger remnant of a tidally destroyed galaxy. We find no optical component associated with the Hi ring. However, observations hint at Hα emission associat...
متن کاملA Note on Restricted Forms of LGG
We study existence of a restricted least general generalization (LGG) with the property that LGGs of clauses from a pre-fixed set belong to this set. We show that there is no such LGG even in simple sets of clauses such as bounded-size clauses or treewidth-1 clauses.
