総研大・国立天文台 スプリングスクール2017

 2月27日(月)~3月2日(木)までの4日間、国立天文台三鷹キャンパスで、総研大・国立天文台スプリングスクールが開校されました。平成23年から始まったスプリングスクール。7回目を迎えた今回は、全国36大学から60名の参加者が集まりました。

最先端の研究者を講師陣として、理論天文学、電波天文学、光赤外線天文学、太陽物理学、装置開発の5つの天文学講義を4日間にわたって受講していただきました。

S-Cam and HSC Search of z>6 Quasars
[Abstract]
I will present several updates on our high-redshift (z>6) quasar search projects using Subaru/S-Cam and HSC.
In short, our constraints on the quasar luminosity function at z~6 suggest that quasars have only a moderate contribution on the total photons required to re-ionize the universe at z~6.
From the HSC-Wide survey, we have found ~30 low-luminosity quasars
at z>6 in ~100 deg^2 of the HSC-SSP coverage. Their NIR follow-up observation is
now ongoing with Gemini and VLT, which is for the BH mass and metallicity measurements.
Moreover, the HSC-Deep survey enables us to find much fainter quasar candidates down to z~25 AB mag.
