もうひとつの見えない粒子「ステライルニュートリノ」

http://www.nikkei-science.com/201805_052.html

ニュートリノは電子型，ミュー型，タウ型の3種類の存在が知られる。それらの質量などに関する情報は，ニュートリノが飛行する間に種類が変わる「ニュートリノ振動」の実験によってかなりわかってきた。ただ一部のニュートリノ振動実験では，未知の種類の存在を示唆する結果が報告されている。他の実験結果との整合性を考えると，未知の種類は既知の3種類と違って，放射性元素の崩壊などを起こす「弱い力」が作用しない「ステライル型」だと考えられている。ステライル型が実在するのかどうか確かめるため，大強度陽子加速器施設「J-PARC」で大がかりな実験が年内にも始まる予定だ。

The High-velocity System: Infall of a Giant Low-surface-brightness Galaxy toward the Center of the Perseus Cluster

http://adsabs.harvard.edu/abs/2015ApJ...814..101Y

Figure 6. Channel maps for the main body (upper set of panels) and secondary body (lower set of panels). The heliocentric velocity of each channel is indicated. Notice the similar overall morphology of the main and secondary bodies in each panel separated by 120 km s−1. The cross in each panel marks the approximate geometrical center of the main body of the HVS. The white rectangle in the lower set of panels corresponds to the region where an outflow associated with the AGN in NGC 1275 is detected; this outflow produces a relatively strong and very broad component in the red wing of the [N ii]λ6583 Å line from NGC 1275, thus obscuring any line emission associated with the secondary body of the HVS. The angular resolution of the maps is 27 at FWHM.
