An old stellar population or diffuse nebular continuum emission discovered in green pea galaxies
Leonardo Clarke, Claudia Scarlata, Vihang Mehta +9
We use new HST images of nine Green Pea Galaxies (GPGs) to study their resolved structure and color. The choice of filters, F555W and F850LP, together with the redshift of the gala…
The Effect of Bi-conical Outflows on Ly Escape From Green Peas
Cody Carr, Claudia Scarlata, Alaina Henry +1
We analyze the spectra of Green Pea galaxies, previously studied by Henry et al. (2015), using a semi-analytical line transfer (SALT) model to interpret emission and absorptio…
Investigating Clumpy Galaxies in the Sloan Digital Sky Survey Stripe 82 using the Galaxy Zoo
Vihang Mehta, Claudia Scarlata, Lucy Fortson +7
Giant, star-forming clumps are a common feature prevalent amongst high-redshift star-forming galaxies and play a critical role in shaping their chaotic morphologies and yet, their…
Searching for Cross-Correlation Between Stochastic Gravitational Wave Background and Galaxy Number Counts
Kate Ziyan Yang, Vuk Mandic, Claudia Scarlata +1
Advanced LIGO and Advanced Virgo have recently published the upper limit measurement of persistent directional stochastic gravitational wave background (SGWB) based on data from th…
Lyman Continuum Escape Fraction from Low-mass Starbursts at z=1.3
Anahita Alavi, James Colbert, Harry I. Teplitz +8
We present a new constraint on the Lyman Continuum (LyC) escape fraction at z~1.3. We obtain deep, high sensitivity far-UV imaging with the Advanced Camera for Surveys (ACS) Solar…
Identification of single spectral lines through supervised machine learning in a large HST survey (WISP): a pilot study for Euclid and WFIRST
I. Baronchelli, C. M. Scarlata, G. Rodighiero +13
Future surveys focusing on understanding the nature of dark energy (e.g., Euclid and WFIRST) will cover large fractions of the extragalactic sky in near-IR slitless spectroscopy. T…
