In recent discovery, detailed modeling of eclipse timing variations (ETVs) of the Post-common-envelope binary has resulted in the claimed detection of multiple circumbinary companions. We combine recent primary eclipse timing observations with previously published values to solve for possible substellar companions that can account for the observed timing variations for three sub-dwarf...
Luminous Red Galaxies, or LRGs, were originally selected in the Sloan Digital Sky Survey as good tracers of large scale structure. Subsequent investigations showed them to be among the most massive galaxies in the Universe and dominated by uniformly old stellar populations. Despite being dominated by old stars, however, they have grown in stellar mass since z=1, implying that they grow...
There is a two sigma discrepancy between the standard model predictions and the experimental values of the anomalous magnetic moment of the muon ($a_{\mu}$). This difference suggests the possibility of beyond the standard model physics. The tau lepton, $\tau$, is 16 times more massive than the muon, $\mu$.
Measuring $a_{\tau}$ would be an even better test of the standard model, since...
Current lithium ion batteries are facing not only a sustainability issue but also an energy density mismatch issue between the cathode and anode. There is a sufficient need to look for alternate materials for this purpose, one such material being V2O5. On top of being able to host lithium it can also host more terrestrially abundant ions such as: Na, Mg, Zn, Ca, K and Al. V2O5 however can...
Crustal magnetic fields were first discovered at Mars by the Mars Global Surveyor (MGS) mission (Acuña et al., 1998). Since then, there have been several crustal field models and maps produced, as well as many missions to Mars to better study the crustal fields. The crustal fields are thought to influence ion loss from the planet, so having a precise understanding of the structure of these...
The physics program of the CERN LHC relies on our description of the interactions of quarks and gluons, the degrees of freedom of quantum chromodynamics (QCD), in high-energy hadronic collisions. When the interactions occur at very short distances, cross sections can be calculated in a power expansion of the strong coupling, $\alpha_s \ll 1$. However, there are regions of phase-space where...
The study of Active Galactic Nuclei (AGN) is important to further our understanding of galaxy evolution, and thus, reliable and accurate methods for the identification of AGN are crucial. With the unprecedented sensitivity of the James Webb Space Telescope (JWST), and in particular, the Mid-Infrared Instrument (MIRI), more reliable and sensitive classification techniques are needed....
In this paper we have discussed a theoretical approach to find out some of the parameters of neutrino oscillations. We have assumed that twice of the sum of the three neutrino mixing angles is ${180}^0$; in other words twice of the three mixing angles constitute a triangle. We have constructed one such triangle with proper scale factor such that among the three sides two are independent mass...
Stars and their planets form from the same cloud of interstellar dust and gas implying a chemical link between the composition of exoplanets and the stars that host them. For the majority of exoplanet hosting stars, however, we only know the bulk metallicity rather than the abundances of particular elements such as magnesium, silicon, oxygen, and carbon. These elements, among others, are...
Using density functional theory (DFT) as implemented in the Vienna Ab initio Simulation Package (VASP) and the Atomic Simulation Environment (ASE) Python module, we will investigate under what conditions Vanadium Pentoxide (V2O5) can be used as a material for chemical gas sensors by simulating adsorption processes for simple molecules such as NH3, CO, H2O, etc. Some experiments have revealed...
Cold Quasars ($ \rm L_x > 10^{44} $ erg/s, $\rm S_{250} > 30$ mJy) are a recently discovered, extremely rare galaxy. They are luminous in both the X-ray and infrared wavelengths and can have up to seven times as much star formation as normal quasars. They are predicted to be a step in the progression between the starburst galaxies that have undergone a recent galaxy merger and blue, unobscured...
