The Halos and Environments of Nearby Galaxies (HERON) Survey IV: Complexity in the boxy galaxies NGC 720 and NGC 2768
Andreas J. Koch-Hansen, Anna Pasquali, R. Michael Rich +2
The shapes of galaxies, in particular their outer regions, are important guideposts to their formation and evolution. Here we report on the discovery of strongly box-shaped morphol…
The Chemical Composition of Red Giant Branch Stars in the Galactic Globular Clusters NGC 6342 and NGC 6366
Christian I. Johnson, Nelson Caldwell, R. Michael Rich +2
We present radial velocities and chemical abundances for red giant branch stars in the Galactic bulge globular clusters NGC 6342 and NGC 6366. The velocities and abundances are bas…
Fast radio bursts: the observational case for a Galactic origin
Dan Maoz, Abraham Loeb, Yossi Shvartzvald +10
There are by now ten published detections of fast radio bursts (FRBs), single bright GHz-band millisecond pulses of unknown origin. Proposed explanations cover a broad range from e…
Light Element Chemistry and the Double Red Giant Branch in the Galactic Globular Cluster NGC 288
Tiffany Hsyu, Christian I. Johnson, Young-Wook Lee +1
The globular cluster NGC 288 was previously reported to exhibit two distinct red giant branches (RGBs) in the narrow-band Calcium (HK) and Strömgren b and y band passes. In order t…
The mass-metallicity relation of galaxies up to redshift 0.35
Ivo Saviane, Irina Yegorova, Dominique Proust +5
Our research on the age-metallicity and mass-metallicity relations of galaxies is presented and compared to the most recent investigations in the field. We have been able to measur…
Transiting extrasolar planetary candidates in the Galactic bulge
Kailash C. Sahu, Stefano Casertano, Howard E. Bond +13
More than 200 extrasolar planets have been discovered around relatively nearby stars, primarily through the Doppler line shifts owing to the reflex motions of their host stars, and…
