[漢羅] 19 擺 ê 重力波頻譜圖

逐改若是有兩个 烏洞相碰，to̍h 會 tī 宇宙發出足大聲 ê 重力波。 人類到 7 年前才有法度聽著這个 特別 ê 聲，毋閣咱已經 tī 前三輪觀測聽著 90 擺事件矣。 這張圖 是頻譜圖，是重力波頻率 kah 時間 ê 關係。 這 90 擺事件是用 LIGO (美國) 、VIRGO (歐洲)、kah KAGRA (日本) ê 大型探測器揣著 ê。 相碰事件 ê 能量 傳到 地球 若是愈強，顯示 tī 圖內底 ê to̍h 會 愈光。 這是科學界新 ê 發展，重力輻射 ê 聲 予咱發現講，烏洞 kah 中子星比咱知影 ê 閣較濟，嘛予咱一个新 ê 方式去 量宇宙 ê 脹大率。 第四輪 ê 重力波觀測 會 tī 2022 年 ê 12 月，會有較懸 ê 敏感度。

[English] Ninety Gravitational Wave Spectrograms and Counting

Every time two massive black holes collide, a loud chirping sound is broadcast out into the universe in gravitational waves. Humanity has only had the technology to hear these unusual chirps for the past seven years, but since then we have heard about 90 -- during the first three observing runs. Featured above are the spectrograms -- plots of gravitational-wave frequency versus time -- of these 90 as detected by the giant detectors of LIGO (in the USA), VIRGO (in Europe), and KAGRA (in Japan). The more energy received on Earth from a collision, the brighter it appears on the graphic. Among many science firsts, these gravitational-radiation chirps are giving humanity an unprecedented inventory of black holes and neutron stars, and a new way to measure the expansion rate of our universe. A fourth gravitational wave observing run with increased sensitivity is currently planned to begin in 2022 December.
