Síntese

GALAH: survey de alta resolução para desvendar a formação da Via Láctea. Apresenta esquema semi-automático (t-SNE) para classificar morfologias espectrais peculiares e flagrar espectros problemáticos, preservando a integridade do survey. Exemplo de detecção de ‘peculiaridades’ espectrais — conexão com anomalias.
