... Seeking a splendid escape to the beach or the cool breezes and green hills of the foothills and mountains of the northeast can offer a chance to take a longer look at the summer sky. ... StarQuest Memories. StarQuest was a blast this year! ... The observing at StarQuest, especially on Saturday night, was worthy of pulling an all-nighter, and several of us had our eyepieces and CCD cameras working all night along (including Brian Van Liew and Bob Vanderbei with their CCDs). ... Dark Skies! ...

Journal of the Amateur Astronomers Association of New York August 2007 Volume 55 Number 8, ISSN 0146-7662 EYEPIECE understand dark matter is to locate it, and observe its structure and function in the universe, and this is what Massey and his team set out to do. ... August's Planets. ... By splitting the half million background source galaxies it observed into discrete redshift bins, Massey's team could visualize a three-dimensional map of the dark matter surrounding them. ...

... The kinematics, structure, and stellar population properties in the centers of two early-type spiral galaxies of the Leo Triplet, NGC 3627 and NGC 3623, are studied by means of integral-field spectroscopy. ... In the center of NGC 3627 we observe noticeable gas radial motions, and the stars and the ionized gas in the center of NGC 3623 demonstrate more or less stable rotation. ... In this work we consider two nearby early-type spiral galaxies belonging to the famous Leo Triplet, NGC 3623 and NGC...

We measure highly significant Baldwin effects for most broad emission lines (C IV 1549, C III] 1909, Mg II 2798, H ,H ) and show that they are predominantly caused by correlations with luminosity, not redshift. ...
