White dwarfs identified in LAMOST Data Release 5
Jincheng Guo, Jingkun Zhao, Huawei Zhang +5
In this paper, we report white dwarfs identified in the 5th Data Release of the Large Area Multi-Object fibre Spectroscopic Telescope, including spectral types of DA, DB, DC, DZ, a…
Extended Tidal Tails of IC 4756 detected by {\it Gaia} EDR3
Xianhao Ye, Jinkun Zhao, Jiajun Zhang +2
We report the discovery of emerged tidal tails around open cluster IC 4756 ( 1 Gyr) based on 644 members identified from {\it Gaia} EDR3. Three-dimensional spatial positions,…
Tracing the Origin of Moving Groups. III. Detecting Moving Groups in The LAMOST DR7
Yong Yang, Jingkun Zhao, Jiajun Zhang +2
We revisit the moving groups (MGs) in the solar neighborhood with a sample of 91969 nearby stars constructed from LAMOST DR7. Using the wavelet technique and Monte Carlo simulation…
Numerical convergence of pre-initial conditions on dark matter halo properties
Tianchi Zhang, Shihong Liao, Ming Li +1
Generating pre-initial conditions (or particle loads) is the very first step to set up a cosmological N-body simulation. In this work, we revisit the numerical convergence of pre-i…
The BINGO Project VI: HI Halo Occupation Distribution and Mock Building
Jiajun Zhang, Pablo Motta, Camila P. Novaes +19
BINGO (Baryon Acoustic Oscillations from Integrated Neutral Gas Observations.) is a radio telescope designed to survey from 980 MHz to 1260 MHz, observe the neutral Hydrogen (HI) 2…
The BINGO Project VII: Cosmological Forecasts from 21cm Intensity Mapping
Andre A. Costa, Ricardo G. Landim, Camila P. Novaes +17
The 21cm line of neutral hydrogen (HI) opens a new avenue in our exploration of the structure and evolution of the Universe. It provides complementary data to the current large-sca…
The BINGO Project V: Further steps in Component Separation and Bispectrum Analysis
Karin S. F. Fornazier, Filipe B. Abdalla, Mathieu Remazeilles +20
Observing the neutral hydrogen distribution across the Universe via redshifted 21cm line intensity mapping constitutes a powerful probe for cosmology. However, the redshifted 21cm…
The BINGO Project IV: Simulations for mission performance assessment and preliminary component separation steps
Vincenzo Liccardo, Eduardo J. de Mericia, Carlos A. Wuensche +21
The large-scale distribution of neutral hydrogen (HI) in the Universe is luminous through its 21 cm emission. The goal of the Baryon Acoustic Oscillations from Integrated Neutral G…
The BINGO Project III: Optical design and optimisation of the focal plane
Filipe B. Abdalla, Alessandro Marins, Pablo Motta +26
The BINGO telescope was designed to measure the fluctuations of the 21-cm radiation arising from the hyperfine transition of neutral hydrogen and aims to measure the Baryon Acousti…
The BINGO Project II: Instrument Description
Carlos A. Wuensche, Thyrso Villela, Elcio Abdalla +41
The measurement of diffuse 21-cm radiation from the hyperfine transition of neutral hydrogen (HI signal) in different redshifts is an important tool for modern cosmology. However,…
The BINGO Project I: Baryon Acoustic Oscillations from Integrated Neutral Gas Observations
Elcio Abdalla, Elisa G. M. Ferreira, Ricardo G. Landim +43
Observations of the redshifted 21-cm line of neutral hydrogen (HI) are a new and powerful window of observation that offers us the possibility to map the spatial distribution of co…
Baryon Acoustic Oscillations from Integrated Neutral Gas Observations: an instrument to observe the 21cm hydrogen line in the redshift range 0.13 z 0.45 -- status update
Carlos A. Wuensche, Elcio Abdalla, Filipe Batoni Abdalla +48
BINGO (BAO from Integrated Neutral Gas Observations) is a unique radio telescope designed to map the intensity of neutral hydrogen distribution at cosmological distances, making th…
