Complete history of the observable 21-cm signal from the first stars during the pre-reionization era
Anastasia Fialkov, Rennan Barkana, Arazi Pinhas +1
We present the first complete calculation of the history of the inhomogeneous 21-cm signal from neutral hydrogen during the era of the first stars. We use hybrid computational meth…
Evidence for a Dayside Thermal Inversion and High Metallicity for the Hot Jupiter WASP-18b
Kyle Sheppard, Avi M. Mandell, Patrick Tamburo +4
We find evidence for a strong thermal inversion in the dayside atmosphere of the highly irradiated hot Jupiter WASP-18b (T, ) based on emission spectrosco…
Constraining Stellar Photospheres as an Essential Step for Transmission Spectroscopy of Small Exoplanets
Benjamin V. Rackham, Arazi Pinhas, Dániel Apai +29
Transmission spectra probe the atmospheres of transiting exoplanets, but these observations are also subject to signals introduced by magnetic active regions on host stars. Here we…
On Signatures of Clouds in Exoplanetary Transit Spectra
Arazi Pinhas, Nikku Madhusudhan
Transmission spectra of exoplanetary atmospheres have been used to infer the presence of clouds/hazes. Such inferences are typically based on spectral slopes in the optical deviant…
Quantifying the Bulk Density of Southern Delta Aquariid Meteoroids: Insights from the Canadian Automated Meteor Observatory
Arazi Pinhas, Zbyszek Krzeminski, Denis Vida +1
Physical properties of ten millimeter-sized meteoroids from the Southern Delta Aquariids (SDA) shower are derived using optical observations from the Canadian Automated Meteor Obse…
HO abundances and cloud properties in ten hot giant exoplanets
Arazi Pinhas, Nikku Madhusudhan, Siddharth Gandhi +1
Transmission spectroscopy of exoplanets has the potential to provide precise measurements of atmospheric chemical abundances, in particular of hot Jupiters whose large sizes and hi…
