Early-type galaxies have low specific star formation rates, old stellar populations, and little cold gas. Luminous Red Galaxies, or LRGs, were originally selected in the Sloan Digital Sky Survey as good tracers of large scale structure. Subsequent investigations have shown them to be among the most massive galaxies in the Universe, dominated by uniformly old stellar populations, and good...
The atmosphere of Mars is CO2 dominated at lower altitudes, below around 225-250km altitude. Through multiple photochemistry paths, the dominant ion species is O2+. Dissociative recombination of O2+ ions produces neutral O atoms which have sufficient energy to escape from the planet. The amount of oxygen lost over geological time periods due to this process is very large(several meters of...
We present the analysis of the Hot Jupiter, TOI-1107b, discovered by the Transiting Exoplanet Survey Satellite (TESS) mission. The mass of the planet, $3.02\pm0.37 M_J$, is determined using the RadVel package, with which 45 radial velocity measurements taken with MINERVA-Australis are analyzed. By analyzing the transiting light curve of the host star using the exoplanet package, we determined...
With the CMS Phase-1 detector nearing the end of its lifetime and the construction of the High-Luminosity LHC in the horizon, technologies for the new Phase-2 detector are approaching completion. One such technology, the so called low-gain avalanche detectors (LGADs), are being designed to provide valuable timing information for proton-proton collisions on an event-by-event basis. As one of...
The large-scale structure of the universe, colloquially known as the cosmic web, consists of a patchwork of dense clusters and low-density “field” regions, with strands of filamentary networks connecting and feeding these central clusters. Observations up until now have demonstrated that these clusters feature a lower fraction of star-forming galaxies relative to the isolated galaxies of the...
The precision of beam energies at LEP, LHC, ILC, FCC-ee will be discussed and compared. A general introduction to the proposed ILC, FCC-ee experiments will also be given. Energy calibration methods of resonant depolarization (RDP) and some "standard candle" energy calibration events will be presented. Emphasis will be given on ILC's Z->mu+mu- method. The experiments are then compared in a...
