Chemical enrichment of stars due to accretion from ISM during the Galaxy's assembly
Sijing Shen, Girish Kulkarni, Piero Madau +1
Using the Eris zoom-in cosmological simulation of assembly of a Milky Way analog, we study chemical enrichment of stars due to accretion of metal-enriched gas from the interstellar…
From Mirrors to Windows: Lyman-Alpha Radiative Transfer in a Very Clumpy Medium
Max Gronke, Mark Dijkstra, Michael McCourt +1
Lyman-Alpha (Ly) is the strongest emission line in the Universe and is frequently used to detect and study the most distant galaxies. Because Lya is a resonant line, photons typ…
Enhanced direct collapse due to Lyman alpha feedback
Jarrett L. Johnson, Mark Dijkstra
We assess the impact of trapped Lyman alpha cooling radiation on the formation of direct collapse black holes (DCBHs). We apply a one-zone chemical and thermal evolution model, acc…

We present the results of ALMA spectroscopic follow-up of a Lyman- emitting galaxy behind the cluster RXJ1347-1145. We report the detection of [CII]158m line fully…
Lens Model and Time Delay Predictions for the Sextuply Lensed Quasar SDSS J2222+2745
Keren Sharon, Matthew B. Bayliss, Hakon Dahle +7
SDSS J2222+2745 is a galaxy cluster at z=0.49, strongly lensing a quasar at z=2.805 into six widely separated images. In recent HST imaging of the field, we identify additional mul…
Boosting Lya and HeII 1640A Line Fluxes from Pop III Galaxies: Stochastic IMF Sampling and Departures from Case-B
Lluís Mas-Ribas, Mark Dijkstra, Jaime E. Forero-Romero
We revisit calculations of nebular hydrogen Lya and HeII 1640A line strengths for population III galaxies, undergoing continuous and bursts of star formation. We focus on initial m…
ALMA observations of Lyman-alpha Blob 1: halo sub-structure illuminated from within
J. E. Geach, D. Narayanan, Y. Matsuda +28
We present new Atacama Large Millimeter/Submillimeter Array (ALMA) 850um continuum observations of the original Lyman-alpha Blob (LAB) in the SSA22 field at z=3.1 (SSA22-LAB01). Th…
Illuminating gas in-/outflows in the MUSE deepest fields: discovery of Ly-alpha nebulae around forming galaxies at z~3.3
E. Vanzella, I. Balestra, M. Gronke +11
We report on the discovery of extended Ly-alpha nebulae at z~3.3 in the Hubble Ultra Deep Field (HUDF, ~ 40 kpc X 80 kpc) and behind the Hubble Frontier Fields galaxy cluster MACSJ…
High-redshift supernova rates measured with the gravitational telescope A1689
Tanja Petrushevska, Rahman Amanullah, Ariel Goobar +12
We present a ground-based near-infrared search for lensed supernovae behind the massive cluster Abell 1689 at z=0.18, one of the most powerful gravitational telescopes that nature…
Planck intermediate results. XLV. Radio spectra of northern extragalactic radio sources
Planck Collaboration, P. A. R. Ade, N. Aghanim +202
Continuum spectra covering centimetre to submillimetre wavelengths are presented for a northern sample of 104 extragalactic radio sources, mainly active galactic nuclei, based on f…

Kuang-Han Huang, Brian C. Lemaux, Kasper B. Schmidt +13
We report the detection of Ly emission at Å in the Keck/DEIMOS and \HST WFC3 G102 grism data from a triply-imaged galaxy at behind galaxy cluster MAC…
Giant Lyman-Alpha Nebulae in the Illustris Simulation
Max Gronke, Simeon Bird
Several `giant' Lyman- (Ly) nebulae with extent kpc and observed Ly luminosity of $\gtrsim 10^{44}\,{\rm erg}\,{\rm s}^{-1}\,{\rm cm}^{-2}\,{\rm arcsec}^{-2…

Lluís Mas-Ribas, Mark Dijkstra
We quantify the contribution of Ly fluorescence to observed spatially extended Ly halos around Ly emitters (LAE) at redshift . The key physical quantities tha…
