Primordial star clusters at extreme magnification
Erik Zackrisson, Juan Gonzalez, Simon Eriksson +4
Gravitationally lensed galaxies with magnification ~10-100 are routinely detected at high redshifts, but magnifications significantly higher than this are hampered by a combination…
Variability of Disk Emission in Pre-Main Sequence and Related Stars. III. Exploring Structural Changes in the Pre-transitional Disk in HD 169142
Kevin R. Wagner, Michael L. Sitko, Carol A. Grady +17
We present near-IR and far-UV observations of the pre-transitional (gapped) disk in HD 169142 using NASA's Infrared Telescope Facility and Hubble Space Telescope. The combination o…
The critical radiation intensity for direct collapse black hole formation: dependence on the radiation spectral shape
Kazuyuki Sugimura, Kazuyuki Omukai, Akio K. Inoue
It has been proposed that supermassive black holes (SMBHs) are originated from direct-collapse black holes (DCBHs) that are formed at z gtrsim 10 in the primordial gas in the case…
The environments of Ly blobs I: Wide-field Ly imaging of TN J1338-1942, a powerful radio galaxy at associated with a giant Ly nebula
Tomoki Saito, Yuichi Matsuda, Cedric G. Lacey +10
We exploit wide-field Ly imaging with Subaru to probe the environment around TN J1338-1942, a powerful radio galaxy with a >100 kpc Ly halo at z=4.11. We used a sample of…
An updated analytic model for the attenuation by the intergalactic medium
Akio K. Inoue, Ikkoh Shimizu, Ikuru Iwata +1
We present an updated version of the so-called Madau model for the attenuation by the intergalactic neutral hydrogen against the radiation from distant objects. First, we derive a…
