How Much Graphene in Space?

Qi Li, Aigen Li, B. W. Jiang

The possible presence of graphene in the interstellar medium (ISM) is examined by comparing the interstellar extinction curve with the ultraviolet absorption of graphene calculated…

Three dimensional dust mapping of 12 supernovae remnants in the Galactic anticentre

Bin Yu, B. Q. Chen, B. W. Jiang +1

We present three dimensional (3D) dust mapping of 12 supernova remnants (SNRs) in the Galactic anti-center (Galactic longitude between 150\degr\ and 210\degr) based on a recent…

Mapping the Galactic disk with the LAMOST and Gaia Red clump sample: III: A new velocity substructure and time stamps of the Galactic disk asymmetry in the disk between 1215 \,kpc

H. -F. Wang, J. L. Carlin, Y. Huang +11

We investigate the three-dimensional asymmetrical kinematics and present time stamps of the Milky Way disk between Galactocentric distances of and 15 \,kpc, using red clump…

The Galactic spiral structure as revealed by O- and early B-type stars

Chen Bingqiu, Huang Yang, Hou Ligang +7

We investigate the morphology and kinematics of the Galactic spiral structure based on a new sample of O- and early B-type stars. We select 6,858 highly confident OB star candidate…

Mapping the Galactic disk with the LAMOST and Gaia Red clump sample. II. 3D asymmetrical kinematics of mono-age populations in the disk between 6 \,kpc

H. -F. Wang, M. López-Corredoira, Y. Huang +11

We perform analysis of the three-dimensional kinematics of Milky Way disk stars in mono-age populations. We focus on stars between Galactocentric distances of and 14 \,kpc, s…

How does the Earth's rotation affect predictions of gravitational wave strong lensing rates?

Lilan Yang, Xuheng Ding, Marek Biesiada +2

The next generation of ground-based gravitational wave (GW) detectors, e.g. the Einstein Telescope, is expected to observe a significant number of strongly lensed GW events as pred…

Dust Extinction towards the Type Ia Supernova 2012cu in NGC 4772

Weijia Gao, Ruining Zhao, Jian Gao +2

Using photometric and spectroscopic data of Supernova (SN) 2012cu, a fairly reddened type Ia supernova, we derived its color excess curves and probed the dust extinction in its hos…

Milky Way tomography with the SkyMapper Southern Survey: I: Atmospheric parameters and distances of one million red giants

Y. Huang, B. -Q. Chen, H. -B. Yuan +7

Accurate determinations of atmospheric parameters (effective temperature , surface gravity log and metallicity [Fe/H]) and distances for large complete samples are…
