Primordial black holes and secondary gravitational waves from chaotic inflation
Gao, Qing
Chaotic inflation is inconsistent with the observational constraint at 68% CL. Here, we show that the enhancement mechanism with a peak function in the noncanonical kinetic term not only helps the chaotic model V(ϕ) = V0ϕ1/3 satisfy the observational constraint at large scales but also enhances the primordial scalar power spe…
The TMRT K band observations towards 26 infrared dark clouds: NH3, CCS, and HC3N
Duan, Yan; Li, Di; Liu, Tie +9 more
We present one of the first Shanghai Tian Ma Radio Telescope (TMRT) K Band observations towards a sample of 26 infrared dark clouds (IRDCs). We observed the (1,1), (2,2), (3,3), and (4,4) transitions of NH3 together with CCS (21–>10) and HC3N J = 2–1, simultaneously. The survey dramatically increases …
