We obtain consistent results from each telescope with a Na amplitude of 521$\pm$161 ppm and 403$\pm$186 ppm for GMOS and KOSMOS respectively.

We highlight several potential pitfalls in exoplanet modeling, including the handling of eccentricity in transit-only fits, that the standard exoplanet convention for $\omega$ uses a left-handed coordinate system, contrary to most modern textbooks, how to avoid an important degeneracy when allowing negative companion masses, and a widely unappreciated, potential 10-minute ambiguity in the reported transit times.

We go through the many considerations involved in fitting a model to data, using as an example the fit of a straight line to a set of points in a two-dimensional plane.

For the stellar population mixing scenario, the abundances of alpha-elements and elements with metallicity-dependent yields dominate the first and second principal components, respectively, and collectively explain 99% of the variance in the model.

Here we present a new method of detecting exoplanet candidates in large planetary search projects which, unlike current methods uses a neural network.

The residuals of fitting a linear orbit ephemeris are used to search for transit timing variations.

Understanding the impact of environment on the formation and evolution of dark matter halos and galaxies is a crucial open problem.

Over the past few decades, the measurement precision of some pulsar-timing experiments has advanced from ~10us to ~10ns, revealing many subtle phenomena.

In this low column density regime, we derive a characteristic value of $N_{\rm HI}/E(B-V) = 8. 8\times10^{21}\, \rm\, cm^{2}\, mag^{-1}$ for gas with $|v_{\rm LSR}| < 90\,\rm km\, s^{-1}$ and find no significant reddening associated with gas at higher velocities.
