원반의 경사가 크게 기울어져 측면은하(edge-on galaxy)로 보이는 경우에 쉽게 관측된다. 국부 우주에서 옆으로 측면은하로 관측되는 원반은하의 약 60%가 뚜렷한 뒤틀림을 보여준다. 은하계 뒤틀림은 중성 수소 관측을 통해 가스 원반에서 먼저 발견되었으며 이후 가시광, 자외선 영역의 관측으로 항성 원반의 뒤틀림도 확인되었다. 그림 1. 거의 옆으로

파동 신호와 입자 신호를 동시에 관측하여 천체 현상을 보다 종합적인 시각으로 이해하려는 천문학 연구의 한 분야이다. 우리가 포착할 수 있는 신호는 전자기파(감마선, 엑스선, 자외선, 가시광선, 적외선, 전파)뿐만아니라 고에너지 우주선 및 중성미자 입자도 포함된다. 또한, 2015년에 처음으로 관측된 블랙홀 쌍성의 병합 과정에서 발생한 중력파가 새로운 형태의 정보를 담은 신호로 대두되었다. 동일한 천체 현상에 대해 입자신호-전자기파, 중력파-전자기파, 중력파-입자신호 또는 모든 포착 가능한 신호를 사용하는 경우를 통틀어 넓은 의미의 다중신호천문학이라고 부를 수 있다.

촉진하도록 최적화되어 높은 특이성을 얻도록 진화되었다. 이러한 특이성은 활성 자리의 아미노산 배열과 기질의 구조에 의해 결정된다. 그리고 활성 자리는 반응 도중에 변형이 될 수 있지만, 최종적으로 재생된다. 따라서 촉매 반응을 수행할 수 있다. 단백질 내 결합 자리와 촉매 자리를 포함한 활성 자리( </p> <div class="related v2">

상호작용에 의존하며, 일반적으로 용액, 공기, 혈액, 조직, 폐수 및 식수 등 다양한 화학종의 활성을 모니터링한다. 화학센서는 분자 인식의 한 형태이며 화학 감지라고도 부른다. 모든 화학센서는 신호 전달 부위(signaling moiety)와 인식 부위(recognition moiety)가 서로 직접 연결되거나 커넥터나 스페이서를 통해 연결되도록 디자인한다.2) 통합(integrated), 트위스트(twist), 간격(spaced) 등의 다양한 방법으로 구성될 수 있다. 여기서, 신호 전달 부위는 신호 변환기 역할을 하여 얻은 정보(화학센서와 분석물 사이의 상호작용이기도 함)를 명확하고 재현 가능한 방식으로 광학적인 응답으로 전환한다. 화학센서의 기본적 </p> <div
