Siena Galaxy Atlas 2020
John Moustakas, Dustin Lang, Arjun Dey +8
We present the 2020 version of the Siena Galaxy Atlas (SGA-2020), a multi-wavelength optical and infrared imaging atlas of 383,620 nearby galaxies. The SGA-2020 uses optical …
ODIN: Where Do Lyman-alpha Blobs Live? Contextualizing Blob Environments within the Large-Scale Structure
Vandana Ramakrishnan, Byeongha Moon, Sang Hyeok Im +16
While many Lyman-alpha Blobs (LABs) are found in and around several well-known protoclusters at high redshift, how they trace the underlying large-scale structure is still poorly u…
New spectroscopic confirmations of Lyman- emitters at z 7 from the LAGER survey
Santosh Harish, Isak G. B. Wold, Sangeeta Malhotra +14
We report spectroscopic confirmations of 15 Lyman-alpha galaxies at , implying a spectroscopic confirmation rate of 80% on candidates selected from LAGER (Lyman-Alpha…
LAGER Ly Luminosity Function at , Implications for Reionization
Isak G. B. Wold, Sangeeta Malhotra, James Rhoads +17
We present a new measurement of the Ly luminosity function at redshift , finding moderate evolution from that is consistent with a fully or largely ionized $z\sim…
A Lyman-α protocluster at redshift 6.9
Weida Hu, Junxian Wang, Leopoldo Infante +21
Protoclusters, the progenitors of the most massive structures in the Universe, have been identified at redshifts of up to 6.6. Besides exploring early structure formation, searchin…
Variations in the width, density, and direction of the Palomar 5 tidal tails
Ana Bonaca, Sarah Pearson, Adrian M. Price-Whelan +8
Stars that escape globular clusters form tidal tails that are predominantly shaped by the global distribution of mass in the Galaxy, but also preserve a historical record of small-…
