2016 Hot Sci @ STScI
Roseanne Cheng  (JHU)
In a tidal disruption event, a star is torn apart by a supermassive black hole, and as a result some of the debris is ejected from the system, while the rest, after traveling far out from the black hole and returning, forms an accretion flow. Rece ...

Antonino Cucchiara  (Space Telescope Science Institute)
I will present a sample of 45 Damped Lyman-? systems (DLA; NHI ? 2×1020cm?2) counterparts (33 detections, 12 upper limits) which host gamma-ray bursts (GRB-DLAs) in order to investigate the properties (star-formation and metallicity) of the galaxies ...

Erik Tollerud (STScI) (STScI, JHU)
Nearby dwarf galaxies provide a host of interesting opportunities to constrain cosmology and galaxy formation. I.e., “near-field cosmology.” I will describe a program combining the GALFA-HI survey, ground-based optical observations, and HST to sear ...

Jorge-Barrera-Ballesteros  (JHU)
We present the stellar surface mass density vs. gas metallicity (?*-Z) relation for more than 500,000 spatially-resolved star-forming resolution elements (spaxels) from a sample of 653 disk galaxies included in the SDSS IV MaNGA survey. We find a ti ...

Jeff Valenti  (STScI)
High-resolution STIS and COS spectra of cool stars with accurately measured angular diameters reveal that near-UV *continuum* fluxes predicted by existing models are too bright by roughly a factor of two. I will argue that the error in predicted cont ...

Scott Fleming  (Space Telescope Science Institute)
gPhoton is a time-tagged database of more than one trillion GALEX UV photon events, produced and archived by MAST. Its accompanying open-source python package allows users to create calibrated light curves and images at user-specified temporal and s ...

2016 Hot Sci @ STScI
Ivelina Momcheva  (STScI)
3D-HST is a 248-orbit spectroscopic survey with the Hubble Space Telescope designed to study galaxy evolution at z>1. Providing the critical third dimension - redshift - via slitless optical and near-IR grism spectra, 3D-HST opens new possibilities f ...

Yacine Ali-Haïmoud  (JHU)
The nature of dark matter remains one of the most nagging problems in cosmology. In this talk I will discuss several existing or potential probes of dark matter. I will start with a well known hot dark matter, massive neutrinos, and discuss their eff ...

Van Dixon (STScI)
In color-magnitude diagrams of globular clusters, stars brighter than the horizontal branch and bluer than the red-giant branch are known as UV-bright stars. Most are evolving from the asymptotic giant branch (AGB) to the white-dwarf cooling curve. ...

Alexandra Greenbaum  (JHU)
Current ground-based extreme adaptive optics coronagraphic instruments are surveying nearby young stars to image planets, circumstellar disks, and low-mass companions. Direct imaging provides the opportunity to capture young planets in the process of ...
