Star Formation Drives Production of Low Energy Cosmic Rays
Ningyu Tang, Jiahao Liu, Di Li +18
For over a century, the origin of low-energy cosmic rays (LECRs), the dominant heaters and ionizers of dense interstellar gas, remains elusive owing to solar modulation and uncerta…
A Spatially Resolved HI Survey of Seyfert Galaxies: the Role of AGN Feedback in Shaping Atomic Gas Reservoirs
Ruitian Li, Xin Wang, Daizhong Liu +19
Active galactic nucleus (AGN) feedback is a key ingredient in galaxy evolution, yet its impact on the cold atomic gas reservoir -- the neutral hydrogen (HI) phase -- remains poorly…
A long decay of X-ray flux and spectral evolution in the supersoft active galactic nucleus GSN 069
X. W. Shu, S. S. Wang, L. M. Dou +3
GSN 069 is an optically identified very low-mass AGN which shows supersoft X-ray emission. The source is known to exhibit huge X-ray outburst, with flux increased by more than a fa…
Young Galaxy Candidates in the Hubble Frontier Fields - III. MACSJ0717.5+3745
N. Laporte, L. Infante, P. Troncoso Iribarren +15
In this paper we present the results of our search for and study of galaxy candidates behind the third Frontier Fields (FF) cluster, MACSJ0717.5+3745, and its paralle…
A possible ultra strong and broad Fe Ka emission line in Seyfert 2 galaxy IRAS 00521-7054
Ying Tan, Junxian Wang, Xinwen Shu +1
We present XMM-Newton spectra of the Seyfert 2 Galaxy IRAS 00521-7054. A strong feature at ~6 keV (observer's frame) can be formally fitted with a strong (EW=1.3+-0.3 keV in the re…
On the X-ray Baldwin Effect in Active Galactic Nuclei Observed by the Chandra High Energy Grating
Xinwen Shu, Junxian Wang, Tahir Yaqoob +2
Using Chandra High Energy Grating (HEG) observations of 32 AGNs, we present a systematic study of the X-ray Baldwin effect (XBE, i.e. the anti-correlation between narrow Fe Kα line…
CLASH: Discovery of a Bright z~6.2 Dwarf Galaxy Quadruply Lensed by MACS J0329.6-0211
A. Zitrin, J. Moustakas, L. Bradley +22
We report the discovery of a z_{phot}=6.18^{+0.05}_{-0.07} (95% confidence level) dwarf galaxy, lensed into four images by the galaxy cluster MACS J0329.6-0211 (z_{l}=0.45). The ga…
Chandra High Energy Grating Observations of the Fe Ka Line Core in Type 2 Seyfert Galaxies: A Comparison with Type 1 Nuclei
Xinwen Shu, Tahir Yaqoob, Junxian Wang
We present a study of the core of the Fe Ka emission line at ~6.4 keV in a sample of type II Seyfert galaxies observed by the Chandra High Energy Grating (HEG). The sample consists…
XMM Observations of the Seyfert 2 Galaxy NGC 7590: the Nature of X-ray Absorption
X. W. Shu, T. Liu, J. X. Wang
We present the analysis of three XMM observations of the Seyfert 2 galaxy NGC 7590. The source was found to have no X-ray absorption in the low spatial resolution ASCA data. The XM…
