A series of scripts were created in Python to isolate and measure the Si II absorption line feature in the spectra of Type Ia supernovae. This line feature was then compared to the rest wave length of Si II, and using the ...
-
(2013-03-24)Microencapsulation of cells is a technique in which cells are enclosed in microscopic spheroids of a desired substance, with applications in many fields, such as biomedical engineering. In this study, a microfluidic approach ...
-
The Large Hadron Collider (LHC), the largest particle accelerator in the world, is planning on upgrading its performance in the upcoming High-Luminosity LHC project. This project will increase the flux of incoming particles ...
-
In recent decades, physicists developed ghost imaging, which is an alternative technique to the conventional imaging used everywhere by cameras. Ghost imaging was given its name because none of the light that reached the ...
-
(2012-04-24)Highly oscillatory integrals of the form $I(f)=\int_{0}^{\infty} dx f(x) e^{i \omega g(x)}$ arise in various problems in dynamics, image analysis, optics, and other fields of physics and mathematics. Conventional approximation ...
-
(2010-07-14)When studying the expansion of the universe, a significant problem is measuring the red shifts of stellar absorption lines with sufficiently high accuracy; this requires extremely accurate reference frequencies for ...
-
(2021-04-28)We attempt to see if strong coupling between a quantum electromagnetic field and Landau quantized (LQ) graphene is achievable. LQ graphene acts as a collection of two-level quantum bits (qubits). This coupling between field ...
-
(2010-01-16)The DIRECT project aims to improve the extragalactic distance ladder by discovering Cepheids and eclipsing binaries in M31 and M33. We present the detection of Cepheids and other variables in M33 based on data obtained by ...
-
Electron beam technology is a growing field with applications in industrial processes, the medical field, and the physical sciences. To accelerate the electrons to the required energy, they are sent through a linear ...
-
Due to excess gravitational force in the observable universe, it is estimated that 85% of the matter in the universe does not interact with electromagnetic, or light, waves. This matter has been dubbed “Dark Matter:”, and ...
-
(2010-07-14)We study the nature and clustering of infrared (IR) galaxies at z~1.5-3 in a 9 deg2 region from the Spitzer Deep, Wide-Field Survey (SDWFS) and the MIPS (Multiband Imaging Photometer for SIRTF) AGN (Active Galactic Nuclei) ...
-
(2014-09-24)The high-luminosity upgrade of the Large Hadron Collider (HL-LHC) scheduled for 2022-2023 focuses on increasing the intensity of proton beams to produce a higher number of collisions per second, making it easier to collect ...
-
Since the dawn of human observation, we have been studying the interaction between light and the rest of the universe. From the harnessing of fire to the use of telephones, humans have been finding new ways to use light ...
-
In light of the recent major upgrades to the Large Hadron Collider (LHC) at CERN in the second long shutdown, the intense experimentation of Run 3 will follow in the coming years. At an energy level of approximately 13.6 ...
-
(2013-09-25)Proper formation of lineage restrictions is important in developing animals to ensure healthy development. While mechanisms that form these restrictions are understood in invertebrates, it is not yet known what contributes ...
-
(2013-02-01)In searches for new fundamental particles in high energy particle collisions, the ability for a detector to select collisions that might signify the presence of such particles is one of the top priorities. Equally important ...
-
(2010-07-14)The anodization of aluminum films grown on silicon substrates under controlled conditions is used to fabricate porous alumina arrays. Such porous arrays are used as sensors or lithography masks for fabrication of sub-100-nm ...
-
(2011-08-08)The properties of surface plasmons (SPs) and their excitation by a light wave are considered. The interaction of light with a metal nanostructure resulted in transmission, reflection and diffraction of light. The spectra ...
-
Observations taken from ground-based telescopes and large spectroscopic facilities are contaminated by emission from the Earth’s atmosphere and must be subtracted from astronomical measurements to recover the true target ...
-
In the very beginning stages of the universe, stars and galaxies began to form in their neutral intergalactic medium (IGM) of Hydrogen. Because these galaxies are clouded in their IGM, Lyman-alpha emission lines are absorbed ...
