NUESTRO OBJETIVO ES ESTUDIAR LA VIABILIDAD DE LA DETECCION DE LAS PRIMERAS GALAXIAS QUE SE FORMARON EN EL UNIVERSO UTILIZANDO UNA INNOVADORA CAMARA INFRARROJA (NIR) A BORDO DE UN MICROSATELITE EN UNA FUTURA MISION ESPACIAL EN ORBITA BAJA. ESTE ESTUDIO DE VIABILIDAD TIENE TRES ASPECTOS: _x000D_ _x000D_ 1) TEORICO: LOS EMISORES LYMAN-ALFA (LAES) SON GALAXIAS JOVENES QUE HAN SIDO OBSERVADAS HASTA UN CORRIMIENTO AL ROJO Z~8, CUANDO EL UNIVERSO TENIA SOLO 0.6 GIGA-AÑOS. LAS OBSERVACIONES DE LAES A Z > 6 SE VEN MUY DIFICULTADAS POR LA PRESENCIA DEL MEDIO INTERGALACTICO QUE NO ESTA AUN PLENAMENTE REIONIZADO, DONDE EL HIDROGENO NEUTRO ABSORBE LOS FOTONES IONIZANTES. NUESTRO EQUIPO HA DESARROLLADO UN SOFISTICADO MODELO DE FORMACION DE GALAXIAS QUE INCLUYE LA FORMACION DE ESTRELLAS DE POBLACION III. SEGUN NUESTRO MODELO, ES MUY PROBABLE QUE LA REIONIZACION HAYA TENIDO LUGAR DOS VECES: UNA PRIMERA A Z=10, DEBIDA A ESTRELLAS DE POB. III QUE DEJARON DE FORMARSE EN ESA EPOCA AL QUEDAR EL ENFRIAMIENTO MOLECULAR DESACTIVADO; Y UNA SEGUNDA Y DEFINITIVA A Z=6, DEBIDA A GALAXIAS JOVENES QUE SE FORMARON A Z>6. DE CONFIRMARSE ESTE ESCENARIO, SERIA POSIBLE OBSERVAR LAES EN TORNO A Z=10. SU DETECCION SUPONDRIA UN HITO DE LA COSMOLOGIA MODERNA Y CONFIRMARIA LA DOBLE REIONIZACION DEL UNIVERSO. NUESTRO OBJETIVO SERIA CARACTERIZAR LA FUNCION TEORICA DE LUMINOSIDAD DE LAES ENTRE Z=6 Y Z=10 Y PREDECIR SUS CARACTERISTICAS FISICAS._x000D_ 2) OBSERVACIONAL: PARA DETECTAR LAES A MUY ALTO Z ES NECESARIO DISPONER DE UNA CAMARA NIR. NUESTRO EQUIPO YA HA COMPLETADO UN PROYECTO PILOTO DE 50 HRS EN GTC OBSERVANDO LAES A Z~6 Y ESTA PREPARANDO UNO SIMILAR A Z~10. SIN EMBARGO, SE NECESITAN ~120 HRS DE GTC PARA OBSERVAR UN AREA DE TAN SOLO ~10 ARCMIN CUADRADOS A 28 MAG AB, LA PROFUNDIDAD MINIMA NECESARIA. ESTAS OBSERVACIONES SE VEN AFECTADAS POR LAS LINEAS ATMOSFERICAS DE OH QUE, ADEMAS DE REDUCIR LA PROFUNDIDAD, OBLIGAN A UTILIZAR UN FILTRO MUY ESTRECHO DISMINUYENDO AUN MAS EL VOLUMEN A EXPLORAR. UNA CAMARA NIR A BORDO DE UN MICROSATELITE OFRECE UNA OPORTUNIDAD UNICA PARA REALIZAR UN ESTUDIO EXHAUSTIVO DE LAES A MUY ALTO Z. CALCULOS PRELIMINARES INDICAN QUE SE PODRIA LLEGAR A 30 MAG AB EN ~50 GRADOS CUADRADOS, PERMITIENDO ASI LA EXPLORACION DE UN VOLUMEN REPRESENTATIVO DEL UNIVERSO. NUESTRO OBJETIVO SERIA IMPLEMENTAR LA MEJOR ESTRATEGIA OBSERVACIONAL PARA LLEVAR A CABO UN CENSO A GRAN ESCALA DE LA POBLACION DE LAES A Z~6 Y A Z~10, INCLUYENDO SIMULACIONES DE LAS OBSERVACIONES CON UNA CAMARA NIR EN EL ESPACIO, ASI COMO EL SOFTWARE DE REDUCCION Y PROCESADO DE IMAGENES. _x000D_ _x000D_ 3) TECNOLOGICO: NUESTRO EQUIPO TIENE ACCESO A UN DISEÑO INNOVADOR DE CAMARA NIR BINOCULAR QUE, CON LIGERAS MODIFICACIONES, SERIA IDONEA PARA OBSERVAR DE MANERA SIMULTANEA LAES A Z~6 Y A Z~10. DICHA CAMARA HA SIDO DISEÑADA ORIGINALMENTE PARA SU INTEGRACION EN UN MICROSATELITE DE 50KGR Y SU UTILIZACION EN MISIONES ESPACIALES TANTO ASTROFISICAS COMO DE OBSERVACION DE LA TIERRA. EN COLABORACION CON EMPRESAS DEL SECTOR AEROESPACIAL ESPAÑOL, NUESTRO EQUIPO TECNOLOGICO YA HA LLEVADO A CABO LA ADAPTACION DEL DISEÑO OPTICO A LOS OBJETIVOS CIENTIFICOS DE ALBA, DEMOSTRANDO EL ENORME POTENCIAL DE ESTA CAMARA. NUESTRO OBJETIVO SERIA DESARROLLAR LA OPTO-MECANICA DE LA CAMARA CON LOS DETECTORES Y ELECTRONICA ASOCIADA, OPTIMIZADA PARA LA ESTRATEGIA OBSERVACIONAL DE ALBA, Y VALIDARLA AL NIVEL DE CUALIFICACION CONOCIDO COMO TRL-6. ESTO DEMOSTRARA LA MADUREZ DEL DESARROLLO DE LA CAMARA PARA SOLICITAR FONDOS PARA UNA MISION ESPACIAL FUTURA A H2020. (Spanish)
