Qinan Wang, Armin Rest, Yossef Zenati +73
We present the 30-min cadence Kepler/K2 light curve of the Type Ia supernova (SN Ia) SN 2018agk, covering approximately one week before explosion, the full rise phase and the decli…
Constraining the swiss-cheese IR-fixed point cosmology with cosmic expansion
Ayan Mitra, Vasilios Zarikas, Alfio Bonanno +2
In a recent work, it has been proposed that the recent cosmic passage to a cosmic acceleration era is the result of the existence of small anti-gravity sources in each galaxy and c…
