Preprint typeset using L ATEX style emulateapj v. 08/13/06 SPITZER OBSERVATIONS OF THE MASSIVE STAR FORMING COMPLEX S254-S258: STRUCTURE AND EVOLUTION
, 2008
"... We present Spitzer-IRAC, NOAO 2.1meter-Flamingos, Keck-NIRC, and FCRAO-SEQUOIA observations of the massive star forming complex S254-S258, covering an area of 25×20 arc-minutes. Using a combination of the IRAC and NIR data, we identify and classify the young stellar objects (YSO) in the complex. We ..."

COSMOLOGICAL MODELS OF MODIFIED GRAVITY
, 2013
"... The recent discovery of dark energy has prompted an investigation of ways in which the accelerated expansion of the universe can be realized. In this dissertation, we present two separate projects related to dark energy. The first project analyzes a class of braneworld models in which multiple brane ..."

. In particular, the Randall-Sundrum model is well-known for achieving an amelioration of the hierarchy problem. However, the basic model relies on Minkowski branes and is subject to solar system constraints in the absence of a radion stabilization mechanism. We present a method by which a four-dimensional low
Recombination coecients for C ii lines?
, 1999
"... Abstract. Eective recombination coecients are given for C ii transitions between doublet states. The cal-culations are carried out in the temperature range 500 − 20 000 K and for an electron density of 104 cm−3. The eects of electron collisions on the excited states are included. The necessary bound ..."

quantum number n 15 and total orbital angular momentum L 4. The eect of moving the resonance features to their experimentally determined positions is also investigated and found to be important at low temperatures. Key words: atomic data | line: formation | H ii regions | planetary nebulae: general 1.
