An Unsupervised Learning Approach for Quasar Continuum Prediction
Zechang Sun, Yuan-Sen Ting, Zheng Cai
Modeling quasar spectra is a fundamental task in astrophysics as quasars are the tell-tale sign of cosmic evolution. We introduce a novel unsupervised learning algorithm, Quasar Fa…
Constraining the Halo Mass of Damped Ly Absorption Systems (DLAs) at using the Quasar-CMB Lensing Cross-correlation
Xiaojing Lin, Zheng Cai, Yin Li +2
We study the cross correlation of damped Ly systems (DLAs) and their background quasars, using the most updated DLA catalog and the Planck 2018 CMB lensing convergence field. Ou…
A detailed study of massive galaxies in a protocluster at z=3.13
Ke Shi, Jun Toshikawa, Zheng Cai +2
We present a detailed study of Near-IR selected galaxies in a protocluster field at z = 3.13. Protocluster galaxies are selected using the available mutliwavelength data with the p…
Microwave Spectro-Polarimetry of Matter and Radiation across Space and Time
Jacques Delabrouille, Maximilian H. Abitbol, Nabila Aghanim +77
This paper discusses the science case for a sensitive spectro-polarimetric survey of the microwave sky. Such a survey would provide a tomographic and dynamic census of the three-di…
Inflation and Dark Energy from spectroscopy at
Simone Ferraro, Michael J. Wilson, Muntazir Abidi +140
The expansion of the Universe is understood to have accelerated during two epochs: in its very first moments during a period of Inflation and much more recently, at , when D…
Dust in galaxy clusters: Modeling at millimeter wavelengths and impact on Planck cluster cosmology
J. -B. Melin, J. G. Bartlett, Z. -Y. Cai +4
We have examined dust emission in galaxy clusters at millimeter wavelengths using the Planck map to constrain the model based on Herschel observations that was u…
Lyman-Alpha Emitter Galaxies at z ~ 2.8 in the Extended Chandra Deep Field-South: I. Tracing the Large-Scale Structure via Lyman-Alpha Imaging
Zhen-Ya Zheng, Sangeeta Malhotra, James E. Rhoads +4
We present a narrowband survey with three adjacent filters for z=2.8--2.9 Lyman Alpha Emitter (LAE) galaxies in the Extended Chandra Deep Field South (ECDFS), along with spectrosco…
The SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Overview and Early Data
Kyle S. Dawson, Jean-Paul Kneib, Will J. Percival +143
The Extended Baryon Oscillation Spectroscopic Survey (eBOSS) will conduct novel cosmological observations using the BOSS spectrograph at Apache Point Observatory. Observations will…
The SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Quasar Target Selection
Adam D. Myers, Nathalie Palanque-Delabrouille, Abhishek Prakash +34
As part of the Sloan Digital Sky Survey IV the extended Baryon Oscillation Spectroscopic Survey (eBOSS) will improve measurements of the cosmological distance scale by applying the…
A physical model for the evolving UV luminosity function of high redshift galaxies and their contribution to the cosmic reionization
Zhen-Yi Cai, Andrea Lapi, Alessandro Bressan +3
[Abridged] We present a physical model for the evolution of the ultraviolet (UV) luminosity function (LF) of high-z galaxies taking into account in a self-consistent way their chem…
PRISM (Polarized Radiation Imaging and Spectroscopy Mission): An Extended White Paper
PRISM Collaboration, Philippe André, Carlo Baccigalupi +140
PRISM (Polarized Radiation Imaging and Spectroscopy Mission) was proposed to ESA in May 2013 as a large-class mission for investigating within the framework of the ESA Cosmic Visio…
A hybrid model for the evolution of galaxies and Active Galactic Nuclei in the infrared
Zhen-Yi Cai, Andrea Lapi, Jun-Qing Xia +7
[Abridged] We present a comprehensive investigation of the cosmological evolution of the luminosity function (LF) of galaxies and active galactic nuclei (AGN) in the infrared (IR).…
Herschel-ATLAS: towards a sample of ~1000 strongly-lensed galaxies
J. González-Nuevo, A. Lapi, S. Fleuren +39
While the selection of strongly lensed galaxies with 500μm flux density S_500>100 mJy has proven to be rather straightforward (Negrello et al. 2010), for many applications it is im…
Probing Population III Stars in Galaxy IOK-1 at z = 6.96 through He II Emission
Zheng Cai, Xiaohui Fan, Linhua Jiang +7
The He II λ1640 emission line has been suggested as a direct probe of Population III (Pop III) stars at high-redshift, since it can arise from highly energetic ionizing photons ass…
Probing Very Bright End of Galaxy Luminosity Function at z >~ 7 Using Hubble Space Telescope Pure Parallel Observations
Haojing Yan, Lin Yan, Michel A. Zamojski +8
We report the first results from the Hubble Infrared Pure Parallel Imaging Extragalactic Survey, which utilizes the pure parallel orbits of the Hubble Space Telescope to do deep im…
